What does 3(7x-5y)-2(4y-x+1) equal

3(7x−5y)−2(4y−x+1)

Distribute:

=(3)(7x)+(3)(−5y)+(−2)(4y)+(−2)(−x)+(−2)(1)

=21x+−15y+−8y+2x+−2

Combine Like Terms:

=21x+−15y+−8y+2x+−2

=(21x+2x)+(−15y+−8y)+(−2)

=23x+−23y+−2

=23x−23y−2

Step-by-step explanation:

g

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
