5x + 2(-3x) = *
A)-11x
B) -x
C) -x^2
D) 11x

B) -x

Step-by-step explanation:

distribute the 2 to -3x to get 5x + (-6x)

combine terms to get -x

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
