Question

If the area of a rectangular garden is 45x2−12x square meters, and it has a length of 3x meters, what is its width?

15x−4
45x2−4
15x−12
15x2−4x

Answer 1

C is the answer I think

Answer 2

Explanation:

Since A = L*W, W = A/L.

45x^2 - 12x (3x)(15x - 4)

Here, A = -------------------- = ------------------ = 15x - 4

3x 3x

This result matches the first possible answer choice.
