Distribute first. 4 times 3x is 12x and 4 times -5 is -20
12x-20+2x=8 now combine your like terms.
14x-20=8 and add 20 to each side
14x=28 divide
x=2

Answer: 9 inches (choice D)</h3>
Work Shown:
V = volume of pyramid
V = (1/3)*(area of base)*(height)
V = (1/3)*(12*10)*h
V = (1/3)*120h
V = 40h
Set this equal to the given pyramid volume 360 cubic inches and solve for h
40h = 360
h = 360/40
h = 9
37.5 miles
divide 25 by 2, that gives you 12.5
multiply 12.5 by 3 to get 37.5
Answer:
B
Explanation:
Exponents outside of the parentheses have to be distributed to all of the terms inside of the parentheses. So, B is equivalent because it is simply just the version that has the exponent distributed.
Is 2x-5y=0 a direct variation
