Help,Please go step by step

Answer:
d.)
Step-by-step 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:
D) [tex]\displaystyle 2(6w - 12) + 2(2w - 4)[/tex]
Step-by-step explanation:
[tex]\displaystyle 3[2w - 4] = w → 6w - 12 = w[/tex]
Now, according to the Perimeter Formula [for rectangles ONLY], [tex]\displaystyle 2w + 2l = P,[/tex]there are twos factored outside each binomial because in a rectangle, there are two sets of parallel sides, therefore our answer is D).
