13. The area of the rectangle shown below is 2x2 - x - 15 square units. What is the width of the rectangle?
2x + 5

width = (x - 3)

Step-by-step explanation:

2x² - x - 15 has two factors, one of which is '2x + 5'

we can find the other factor to be 'x - 3', which represents the width

b. 24 mm

step-by-step explanation:

use the pythagorean theorem.

a^2 + b^2 = c^2

a^2 + 7^2 = 25^2

a^2 + 49 = 625

a^2 = 576

a = 24

answer: b. 24 mm
