Answer:

Width = a^2 + 2a - 3

Step-by-step explanation:

Given

Area = 5a^4 + 10a^3 - 15a^2

Length = 5a^2

Required

Determine the Width

The area of a rectangle is calculated using:

Area= Length * Width

Make Width the subject

Width = \frac{Area}{Length}

Substitute values for Area and Length

Width = \frac{5a^4 + 10a^3 - 15a^2}{5a^2}

Factorize the numerator

Width = \frac{5a^2(a^2 + 2a - 3)}{5a^2}

Width = a^2 + 2a - 3

Hence, the polynomial for the width of the rectangle is:

Width = a^2 + 2a - 3

Dovator [93]

Step-by-step explanation:

First we will multiply 4 by 12 = 48

Then we will find the factors of 48 that when we add or subtract it the answer is 2 so

12x 2 - 6x + 8x - 4

6x ( 2x - 1) + 4 (2x - 1)

So ( 2x - 1) and (6x + 4) are the factors

Option C is the correct answer
