o a. 4x + 4x + 3
o b. 3x4 + 4x+3
o c. 4x2+3x+4
o d. 4x2 + 3x+4
for apex!

C/D, which you wrote the same answer.

4x² + 3x + 4

Step-by-step explanation:

The two polynomials are added, so we can remove the brackets:

(x² + 2x + 3) + (3x² + x + 1)

= x² + 2x + 3 + 3x² + x + 1

= x² + 3x² + x + 2x + 1 + 3   <=rearrange by like terms (same variable)

= 4x² + 3x + 4   <=after collecting like terms

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
