If f (x)=x 3 + 2x 2 - 3, what is f (-1)?

f(x)= x³+2x²-3

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

f(-1)= -2 is the right answer.

answer: a

step-by-step explanation:

10.2 units

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
