Question

Help,Please go step by step​

Answer 1

d.)

Explanation:

2w-4 is the length and the width is 3x that so:

3(2w-4)=6w-12

thats one side so the equation would be

2(2w-4)+2(6w-12)

we have the 2's in front of the parenthesis because theres two sides with length and two sides with width

Answer 2

D)
`\displaystyle 2(6w - 12) + 2(2w - 4)`

Explanation:

`\displaystyle 3[2w - 4] = w → 6w - 12 = w`

Now, according to the Perimeter Formula [for rectangles ONLY],
`\displaystyle 2w + 2l = P,`there are twos factored outside each binomial because in a rectangle, there are two sets of parallel sides, therefore our answer is D).
