Help with a correct

23 and 31

Step-by-step explanation:

substitute x = 2 into f(x) and x = 4 into g(x)

f(2) = 2(2) - 3 = 4 - 3 = 1

g(4) = 5(4) + 2 = 20 + 2 = 22

Then

f(2) + g(4) = 1 + 22 = 23

substitute x = 8 into f(x) and x = 2 into g(x)

f(8) = 5(8) - 3 = 40 - 3 = 37

g(2) = 3(2) = 6

Then

f(8) - g(2) = 37 - 6 = 31

-14

step-by-step explanation:

2x2 – 2(x+4)

=2x2-2（5+4）

=4-2×9

=4-18

=-14

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
