Answer:
Step-by-step explanation:
First, open the brackets.
(2x + 4) + (-7 - 3b) + (5 - 8x)
= 2x + 4 -7 - 3b + 5 -8x
Simplify the like terms.
= 2x - 8x - 3b + 4 -7 + 5
= -6x - 3b + 2
A swimming pool is shaped like a cylinder with a radius of 15 feet and a height of 6 feet
Answer:
4239 cubic feet
Step-by-step explanation:
V=[tex]\pi[/tex][tex]r^{2} *h[/tex]
V=3.14*225*6
V=3.14*1350
V=4239
Use the grouping method to factor this polynomial.
3+2x2 +7 x + 14
Answer:
7 ( x + 3 )
Step-by-step explanation:
Use order of operations to multiply first.
3+2x2 +7 x + 14
3+4 +7 x + 14
Now group like terms.
3+ 7x + 4 + 14
Add like terms
7x + 21
Find the two multiples of 21.
7x + 7 x 3
Now factor out the 7.
7( x + 3 )
A piece of fabric shaped as a trapezoid has a
height of 14 inches, and bases that measure
16 inches and 9 inches. What is the area of
the fabric?
Answer:
Area of the fabric = 175 square inches
Step-by-step explanation:
Area of a trapezoid = (b1 + b2)/2 * h
Where,
b1 = 16 inches
b2 = 9 inches
h = 14 inches
Area of a trapezoid = (b1 + b2)/2 * h
= (16 + 9)/2 * 14
= 25/2 * 14
= 12.5 * 14
= 175 square inches
Area of the fabric = 175 square inches

Answer:
x = 3.33
y = -2
Step-by-step explanation:
x(4) + 7 = 20
4x +7-7 = 20-7
4x = 13
x = 3.33
(y+7)(4) = 20
y+7 = 20/4
y+7 = 5
y = -2

here is the proportion I used to get the answer. hopefully this helps
Y/2+1/4=y/6
please help solve for y
Answer:
[tex]y = \frac{-3}{4}[/tex]
Step-by-step explanation:
[tex]\frac{y}{2} + \frac{1}{4} = \frac{y}{6}[/tex]
Lets take all the variable terms in L.H.S & all the constant terms in R.H.S.
(While taking a term from one side to another side , it's sign changes )
⇒ [tex]\frac{y}{2} - \frac{y}{6} = -\frac{1}{4}[/tex]
Now in L.H.S. , lets solve the fractions and reduce its numerator and denominator .
⇒ [tex]\frac{3y - y}{6} = -\frac{1}{4}[/tex]
⇒ [tex]\frac{2y}{6} = -\frac{1}{4}[/tex]
⇒ [tex]\frac{y}{3} = -\frac{1}{4}[/tex]
Lets multiplying 3 on both the sides .
⇒ [tex]\frac{y}{3} \times 3 = -\frac{1}{4} \times 3[/tex]
⇒ [tex]y = \frac{-3}{4}[/tex]

The first statement is true because they have congruent angles.
The side length does not matter here because it's useless unless you're trying to find the perimiter of a triangle, which has a completely different algorithm. It is called the Pythagorem Theorum. I just learned the Pythagorem Theorum last class, and it isn't too difficult once you get the hang of it. Wow I went off course. Anyways I hope this helps!
