All of the following are equivalent, except

2x + x

x(2 + 1)

2x²

3x

2x+x = 2x^2

X(2+1) = 2x^2

2x^2 stays the same

Therefore the answer is d 3x is not the same as the rest

a: 1/6, j: 1/4

step-by-step explanation: you are welcome

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
