Solve, showing all work : ( 5x2+3x+4) − (2x2+5x-1)

Step-by-step explanation:

(5x2+3x+4)-(2x2+5-1)=0

(10+3x+4)-(4+5-1)=0

(14+3x)-(8)=0

(14)-(8)=3x

6=3x

x=2

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
