Question

10. A new fish tank has a volume of 10x2 + 30x -40 cubic inches. Assuming V =

LWH, determine the expressions of the length, width and height of the fish tank.

Answer 1

9514 1404 393

Answer:

10, (x+4), (x -1)

Explanation:

The given volume expression can be factored as ...

V = 10x² +30x -40

= 10(x² +3x -4)

= 10(x +4)(x -1)

The expressions representing length, width, and height might be ...

10, (x+4), (x -1)
