Question

An aquarium has a volume of 60,480in^3. The aquarium has a height of 36 inches and a length of 4 more inches than twice the width. Find the length and width of the aquarium.

Answer 1

x= width
y= length

Answer 2

"length of 4 more inches than twice the width"

means

y = x+4

Answer 3

Volume

V = L*W*H

V = y*x*36

V = (x+4)*x*36

V = 36x^2 + 144x

60480 = 36x^2 + 144x

keep going to solve for x

Answer 4

4 more than twice the width, wouldn't that be y = 2x + 4?

Answer 5

oh right, my bad

Answer 6

so it would be

V = (2x+4)*x*36
