Simplify 2 x squared - y for x=3 and y=-2

22

Step-by-step explanation:

2x^2 - y     when x + 3 and y = -2

2(3)^2 - (-2)

2(9) + 4

18 + 4

22

c is the correct answer

step-by-step explanation:

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
