8.which property justifies the fact that 5 (x-2) is equivalent to 5x-10?
a. commutative b. associative c. distributive d. identity

9.which of the following is equivalent to the expression below? 4x+3(2x-1)-4x
a.6x-3 b.6x+3 c.14x-3 d.14x+3

I am pretty sure it is distibutive property

Step-by-step explanation:

To “distribute” means to divide something or give a share or part of something. According to the distributive property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.

it would be 6xy and -16xy.

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
