Given: 3x + 2y + 7 = 5x +3y +10
Prove: m = -2
(Hint: slope)

3x + 2y = -2

Reason: This is because 3x + 2y = 10 for the variable y. 3x-10= 2y.

Since

3x + 7 = -2

Reason: This is because 3x+10= 2y

step-by-step explanation:

ask goog great chance of finding the solution there

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
