Subtract and simplify: (3x2 + 5x – 4) – (2x2 – 7x – 1)

Original: (3x2 + 5x – 4) – (2x2 – 7x – 1)

3x^2 + 5x - 4 - 2x^2 - 7x - 1 < (Took parenthesis off)

First: Do 3x^2 - 2x^2 = x^2

x^2 + 5x - 4 - 7x - 1

Secondly: Do 5x - 7x = -2x

x^2 - 2x - 4 - 1

Third: Do -4 - - 1 = -4 +1 (Note: Subtracting 2 negatives will make it a positive) 

x^2 - 2x -3

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
