Dean needs 60 inches of wood to build a rectangular picture frame. the length l of the frame is twice its width w. three of these equations give the correct value for w. which equation does not?

a)
2·(2w+w)=60

b)
w+2w+w+2w=60

c)
2·w+2·2w=60

d)
w+2w=60

D) W + 2W = 60

Step-by-step explanation:

Let L represent the length of the frame

Let W represent the width of the frame.

From the question, the relationship between L and W is

L = 2W

Also, he question states that 60 inches of wood is needed to build the frame and the frame is rectangle.

This means the perimeter of the frame is 60inches

Perimeter of a rectangle = 2(L+W)

So, we have

2(L + W) = 60 --- open bracket

Replace L with 2W

2(2W + W) = 60 --- here option A is right

Open the bracket

2.2W + 2W = 60 ( dot (.) represent multiplication) --- here, option Cks right

Split the able equation

2W + 2W + 2W = 60 --- continue splitting

W + 2W + 2W+ W = 60 --- here, option B is right.

Hence, option D is the incorrect option.

the answer is c. 23/3
