Which expression is equivalent to (7x−5)−(3x−2)?
A. 10x−7
B. 10x−3
C. 4x−7
D. 4x−3

D. 4x-3

Step-by-step explanation:

First you subtract the 7x and 3x to get 4x.

Then you subtract the -5 and the -2 to get -3

Therfore, your answer is D

-2

7 - 9 = -2

reversed:

-2 + 9 = 7

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
