Answer:

d. 3 in

factor of 15 is 3 and 5

length is 5

solution:

l= w+2

l= 3+2

l=5

then width is 3

Answer:

D. 3inch

Step-by-step explanation:

Given:

length= x+2

width= x

area= 15

Solution:

let rectangle area as A

let lenght as L

let width as W

so

A= (L)(W) --->>> formula of rectangle area

so Substitute and put the given

15= (x+2)(x)

15=x²+2x

x²+2x-15=0

Factor out:

(x-3)(x+5)=0

x-3= 0

x=3

x+5=0

x= -5 since there is no negative value on width.. the answer is 3
