Simplify (3a3 – 7a2 + a) – (6a3 – 4a2 – 8). a. -3a6 – 3a4 + a +8 b. -3a6 – 11a4 +a -8
c. -3a3 – 11a+a -8 d. -3a3 – 3a² + a +8

d. -3a3 – 3a² + a +8

Step-by-step explanation:

Simplify the expression.

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
