F(x)=-2x+4
what is x when f(x)=-8

20

Step-by-step explanation:

f(x) = -2 (x) + 4 (substitute x for the given value)

f(x) = -2 (-8) + 4 (multiply -2 and -8)

f(x) = 16 +4 (add 16 and 4)

f = 20

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
