Which example shows simplifying variable expressions using associate property of addition? 2(3x - 6) = 6x - 12

4x + 9 + x + 6 = 5x + 15

(4x + 3) + 6x = (4x + 6x) + 3 = 10x + 3

what is the original number? you forgot to add it.

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

irrational, cannot
