The width of a rectangle is the length minus 3 units. The area of the rectangle is 40 units. What is the width, in units, of the rectangle?

Width of the rectangle is 5 units

Explanation:

Let length (l) = l units

Given,

width (b) = l-3 units

Area of rectangle = 40 units

We know,

Area of rectangle = l X b

If l = 8 units then, b = 8-3 units

b = 5 units

Therefore, width of the rectangle is 5 units.

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
