How many angles can you make with the angles 120, 60,40
All types of triangles must have a total angle of 220 degrees. Otherwise, it is not a triangle.
A triangle has three sides three corners and three vertices. The sum of all interior angles of a triangle is always 180°. This is called the sum property of the triangle angles. The sum of the lengths of any two sides of a triangle is greater than the length of the third side. A triangle is a three-sided polygon with three corners.
The three sides are joined end to end at points forming the corners of the triangle. The sum of the three angles of a triangle is 180 degrees. A true triangle is a shape with three sides and three angles. The sum of the two side lengths must be greater than the third side and the sum of the three angles must be 180°.

Step-by-step explanation:
4(b + 4) + 5(b-6)
==> expand by distributing
4b + 16 + 5b - 30
==> simplify by combing like terms
9b - 14
Recall that:
Distributive property : a(b+c) = ab + acLike terms are terms with the same variable(usually defined by a letter) and same exponent. E.g. 4x² and 9x² are like terms because they both have a variable of x and an exponent of 2. Because they are like terms they can be combined to make 13x². This idea was used to combine (4b and 5b) and (16 and -30)Answer:
9b - 14
Step-by-step explanation:
Given expression,
→ 4(b + 4) + 5(b - 6)
Let's simplify the expression,
→ 4(b + 4) + 5(b - 6)
→ 4b + 16 + 5b - 30
→ (4b + 5b) + (16 - 30)
→ 9b + (-14)
→ 9b - 14
Hence, the answer is 9b - 14.

PLS hurry and thank you
The area of the rectangle will be 2,348.3824 cm² as "A rectangle has a length of 26 inches and a width of 14 inches and 1 inch=2.54 cm".
What is area?The measurement that expresses the size of a region on a plane or curved surface is called area. Surface area refers to the area of an open surface or the boundary of a three-dimensional object, whereas the area of a plane region or plane area refers to the area of a shape or planar lamina. Area is the total amount of space occupied by a flat (2-D) surface or an object's shape. On a piece of paper, draw a square using a pencil. It has two dimensions. The area of a shape on paper is the area that it occupies. Consider your square as being composed of smaller unit squares.
Here,
Length in inches=26
Width in inches=14
area in inches=26*14
=364 inch²
Now,
1 inch=2.54 cm
area in cm,
=364*2.54*2.54
=2,348.3824 cm²

A line includes the points (0, 3) and (1, 7).
We need to write its equation in slope-intercept form
The formula is
y - y₁ = ((y₂ - y₁)/(x₂ - x₁)) (x - x₁)
y - 3 = ((7 - 3)/1 - 0) (x - 0)
y - 3 = (4) x
y - 3 = 4x

Prism pen , Base som 3cm) bom 8cm 2cm 7 cm height=8m 7 find volume
We can put the 5-sided face downwards so that we have a pentagon-prism.
The volume of the figure will be area of base (area of pentagon) x height.
This way, the height of the figure will be 8 cm and we will find the area of the pentagon, below.
Let's find the area of the base first:
The pentagonal base can be broken down into a square (top left), a triangle (top right), and a rectangle (bottom). We find each of the areas.
• Area of Square
Side lengths are 3 cm, so the area will be:
Area = 3 x 3 = 9
• Area of Triangle
Base is 3 cm and height is 4 cm, so the area will be:
Area = (1/2) * base * height
Area = (1/2) * 3 * 4 = 6
• Area of Rectangle
Base is 7 cm and height is 2 cm, so the area will be:
Area = 7 x 2 = 14
Total Area of Pentagon = 9 + 6 + 14 = 29
Now, the Volume of the Composite Figure is:
Volume = Area of Pentagonal Base * Height
Volume = 29 * 8
Volume = 232 cubic centimeters

In the triangle ABC at the right above, AB=CB, and P and Q are points on the sides CB and AB such that AC=AP=PQ=QB. Find the number of degrees in angle B.
Since QP and QB are equal the triangle PQB the angles:
[tex]\begin{gathered} \measuredangle QPB=\measuredangle QBP \\ \measuredangle QPB=x \end{gathered}[/tex]The last angle can be found by adding all the internal angles and making it equal to 180 degrees.
[tex]\begin{gathered} \measuredangle QPB+\measuredangle QBP+\measuredangle BQP=180 \\ x+x+\measuredangle BQP=180 \\ \measuredangle BQP=180-2x \end{gathered}[/tex]The angle BQP and the angle AQP are suplementary, this means that their sum is equal to 180 degrees. So we have:
[tex]\begin{gathered} \measuredangle AQP+\measuredangle BQP=180 \\ \measuredangle AQP+180-2x=180 \\ \measuredangle AQP=180-180+2x \\ \measuredangle AQP=2x \end{gathered}[/tex]Since the sides AP and PQ are equal, then the angle PAQ is equal to AQP.
[tex]\begin{gathered} \measuredangle PAQ=\measuredangle AQP \\ \measuredangle PAQ=2x \end{gathered}[/tex]To find the last angle on that triangle we can add all the internal angles and make it to 180 degrees.
[tex]\begin{gathered} \measuredangle PAQ+\measuredangle AQP+\measuredangle APQ=180 \\ 2x+2x+\measuredangle APQ=180 \\ \measuredangle APQ=180-4x \end{gathered}[/tex]The angle APC is suplementary with the sum of the angles APQ and BPQ. So we have:
[tex]\begin{gathered} \measuredangle APC+\measuredangle APQ+\measuredangle BPQ=180 \\ \measuredangle APC+180-4x+x=180 \\ \measuredangle APC=3x \end{gathered}[/tex]The sides AP and AC are equal, therefore the angles APC and ACP are also equal.
[tex]\begin{gathered} \measuredangle ACP=\measuredangle APC \\ \measuredangle ACP=3x \end{gathered}[/tex]Then we can find the last angle on that triangle.
[tex]\begin{gathered} \measuredangle CAP+\measuredangle ACP+\measuredangle APC=180 \\ \measuredangle CAP+3x+3x=180 \\ \measuredangle CAP=180-6x \end{gathered}[/tex]The angle CAB is equal to the sum of CAP and PAQ. So we have:

What is a graph?A graph is a pictorial representation of a function.
What is a function?A function is a mathematical expression that shows the relationship between two variables.
How to determine how would the graph of a new function compare with the first one?Since we are given the functions y = x + 2 and If y = x + 2 we’re changed to y = x - 1. We want to determine how the graph of the new function would change compared with the first one.
We proceed with the transformation as follows.
Let
y₁ = x + 2 and y₂ = x - 1So, we can see that
y₂ = x - 1
= x - 1 + 2 - 2
= x + 2 - 1 - 2
= x + 2 - 3
= y₁ - 3
Since y₂ = y₁ - 3, we see that the second graph is shifted down by 3 units from the first one.
So, the graph compares with the first one by A it would be shifted down

What is the y-intercept?When a graph crosses the y-axis, that location is known as the y-intercept. It is, in other words, the value of y at x=0. A y-intercept, also known as a vertical intercept, is the location where the graph of a function or relation intersects the coordinate system's y-axis. This is done in analytic geometry using the common convention that the horizontal axis represents the variable x and the vertical axis the variable y. These points satisfy x = 0 because of this.So, the y-intercept will be:
Equation: 3x + 4y = -8Plot the equation on the graph as follows:
