The greatest common factor(gcf) of the given expression is 3xy.
The expression is 6x²y - 12xy + 9x³y².
From all the terms we take the coefficients. 6 ,12 and 9
The GCF of these three numbers is 3 as it divides all the three numbers.
Now for the variable x. the lowest power will be the gcf. Hence the gcf will have x.
Now for the variable y. the lowest power will be the gcf. Hence the gcf will have y.
Therefore the gcf of the given expression will be 3xy .
6x²y - 12xy + 9x³y² = 3xy (2x - 4 + 3x²y)
The HCF, or highest common factor, is the largest number that divides each of the two or more numbers. HCF is also known by the titles The Greatest Common Measure (GCM) and The Greatest Common Divisor (GCD).
The smallest common multiple of any two or more numbers is found using the least common multiple, or LCM. There are two distinct methods: LCM and HCM. The HCF of two numbers is the highest factor that will exactly any divide two integers equally.
It is the most effective divisor for any pair of integers that may evenly or completely divide the inputted numbers.

find the length of one side of a solid cube given that its
volume is 8 cm cube
total surface area is 54 cm square.
Step-by-step explanation:
I assume you mean as second question "what is the volume of a cube with the surface area of 54 cm² ?".
first question :
volume is 8 cm³
the volume of a cube is side³.
8 cm³ = side³
side = cubic root(8) = 2 cm
add-on : the surface of a cube (6 sides) is 6 times the area of side² squares.
surface = 6 × 2² = 6 × 4 = 24 cm²
second question :
54 cm² = 6 × side²
9 = side²
side = sqrt(9) = 3 cm
and the volume would be
side³ = 3³ = 27 cm³

ANSWER :
Two ordered pairs (Solution) : (-4, -4) and (-3, -3)
Two ordered pairs (Not a solution) : (1, 1) and (2, 3)
EXPLANATION :
From the problem, we have :
[tex]\begin{gathered} y\ge3x+3 \\ y<-2 \end{gathered}[/tex]Note that the boundary line is dashed or broken if the inequality symbol is < or >.
Otherwise, the boundary line is a solid line.
Graph the first inequality :
Change the symbol to "="
[tex]y=3x+3[/tex]Solve for the x and y intercepts.
[tex]\begin{gathered} \text{ when x = 0 :} \\ y=3(0)+3=3 \\ \\ \text{ when y = 0 :} \\ 0=3x+3 \\ -3x=3 \\ x=-\frac{3}{3}=-1 \end{gathered}[/tex]Test the inequality at the origin (0, 0)
The region will pass through the origin if it satisfy the inequality.
[tex]\begin{gathered} y\ge3x+3 \\ 0\ge3(0)+3 \\ 0\ge3 \\ \text{ False!} \end{gathered}[/tex]Therefore, the region will NOT pass through the origin.
Plot the points (0, 3) and (-1, 0).
Connect it with a solid line.
The region will NOT pass the origin.
Graph the second inequality :
Change the symbol to "="
[tex]y=-2[/tex]Since y must be less than -2, the region is from y = -2 to the negative infinity.
Plot the point (0, -2) and draw a horizontal dashed line since the symbol is <.
That will be :
The solution to the inequality is the overlapping region.
Any point in the overlapping region is a solution.
Two ordered pairs solution are (-3, -3) and (-4, -4)
Two ordered pairs that are NOT a solution : (1, 1) and (2, 3)

We are given the following information
Carlos works a total of 86 hours in four weeks.
He works 18.5 hours each week for three weeks.
To determine how many hours Carlos work in the fourth week, we can set up the equation
[tex]86=18.5(3)+x[/tex]We can make x the subject of the formula
[tex]\begin{gathered} x=86-18.5(3) \\ x=86-55.5 \end{gathered}[/tex]Simplifying further
[tex]x=30.5[/tex]Therefore in the fourth week, Carlos will work 30.5 hours

10. 30
Step-by-step explanation:
The sum of the interior angles of a tringle is 180°. The smaller tringle on the right adds up to 180.
One angle is 90, that is the angle that has a small square. Another angle is 55 so the last angle needs to be 35 (90+ 55+35 = 180)
The larger triangle is 25 (90 + 55 + 10 + 25 = 180)
6 m= the sum of the other two angles that are given
10 140 = 90 + 1
1 = 30
Answer:
Step-by-step explanation:
I think you are trying to answer #7 ? I'll do that one
I see that you knew X =35°
and you knew that b/c it's always 180° around the inside, or interior , or minor angles of the RIGHT triangle (i'm making a big point out of the triangle being a "Right" one, b/c it matters for what we know about the triangle.)
so now you can add 10° to the 55° to get the next bigger RIGHT triangle.
65° is the upper angle so the ∠z = 25°
also you know [tex]y^{0}[/tex] b/c you know [tex]x^{0}[/tex] = 35° and
[tex]y^{0}[/tex] + [tex]x^{0}[/tex] = 180 , again
[tex]y^{0}[/tex] = 180-35
[tex]y^{0}[/tex] = 145°

Write a system of two linear equations in two variables that you can
solve by subtracting the equations and that results in a solution of (3, 1).
The system of two linear equations in two variables that we can solve by subtracting the equations and that results in a solution of (3, 1) is:-
x + y = 4
2x - 3y = 3
Let x + y be equation (1) and 2x - 3y = 3 be equation (2).
Multiplying (1) by 2, we get,
2x + 2y = 8 ...(3)
(3) - (2), we get,
(2x - 2x) + (2y - (-3y)) = 8 - 3
0 + 5y = 5
y = 5/5 = 1
y = 1
Putting y = 1 in (1), we get
x + 1 = 4

which description shades length of the number line below?
Given the number line, it appears that in every 1/2 of a number, there are 5 bars in it. And in every 5 bars, 4 bars were shaded.
Adding the number of shades, we get:
4 + 4 + 4 = 12
Adding the total number of bars, we get:
5 + 5 + 5 = 15
The total number of bars sums up to be 3/2 in the number line.
Putting this into an equation, we get:

What is number line?A number line is a diagram of a graduated straight line used to represent real numbers in elementary mathematics. It is assumed that every point on a number line corresponds to a real number, and that every real number corresponds to a point. A number line is a visual representation of numbers on a straight line in mathematics. A number line's numbers are arranged in a sequential manner at equal intervals along its length. It is typically represented horizontally and can extend indefinitely in any direction. A number line is exactly what it sounds like—a horizontal, straight line with numbers spaced evenly apart along its length.

hall. The flag pole is located at D', a reflection of D across the y-axis. The campfire is located at D", a reflection of D'
across the x-axis.
Identify the ordered pair that describes the location of the campfire. Express your answer using decimal notation.
The coordinates of the campfire is D'' ( x₂ , y₂ ) = D'' ( 4.5 , -4.5 )
What is Reflection?
Reflection is a type of transformation that flips a shape along a line of reflection, also known as a mirror line, such that each point is at the same distance from the mirror line as its mirrored point. The line of reflection is the line that a figure is reflected over. If a point is on the line of reflection then the image is the same as the pre-image. Images are always congruent to pre-images
The reflection of point (x, y) across the x-axis is (x, -y). When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is taken to be the additive inverse. The reflection of the point (x, y) across the y-axis is (-x, y)
Given data ,
Let the coordinates for the dining be = D (x , y )
Let the coordinate of the point D (x , y ) be = D ( -4.5 , 4.5 )
Now ,
The coordinates for the flag pole is D'
where D' ( x₁ , y₁ ) is the reflection of D (x , y ) across the y-axis
So , When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is taken to be the additive inverse. The reflection of the point (x, y) across the y-axis is (-x, y)
Therefore , D' ( x₁ , y₁ ) = D' ( 4.5 , 4.5 )
Now ,
The coordinates for the campfire is D'' ( x₂ , y₂ )
where D'' ( x₂ , y₂ ) is the reflection of D' ( x₁ , y₁ ) across the x-axis
So , When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is taken to be the additive inverse. The reflection of the point (x, y) across the x-axis is (x, -y)
Therefore , D'' ( x₂ , y₂ ) = D'' ( 4.5 , -4.5 )
Hence , The coordinates of the campfire is D'' ( x₂ , y₂ ) = D'' ( 4.5 , -4.5 )
