What is the base width of a rectangular pyramid, if its length, height and volume are 7 cm, 4 cm, and 112 cm3 respectively? a. 12 cm
b. 7 cm
c. 4 cm
d. 17 cm

i think it would be 42cm

apex answer is: true.

if y=4x then you will substitute 4x in for y in the second equation.

8x + 4x = 18 combine like terms

12x = 18 divide by 12 on both sides

x = 18/12 or 3/2

now replace x in the first equation with 3/2 to get

y = 4 3/2

y = 6

the answer is a

(3/2,6)

hope that .
