Answer:

26 cm

Step-by-step explanation:

we can make an equation to find the lengths

2(x+7x-2) = 60

x : length of width

7x-2 : the length of length

2 : the two pairs of length and width

solving this equation, we get x = 4

but that is not the answer

we have to plug in x=4 into 7x-2

7*4-2 = 28-2 = 26

Answer:

I am not entirely sure what you are asking here but if I am right then the answer is -4(x-2) = 8 - 4x

Step-by-step explanation:

Multiplying binomials all you have to do is distribute the 4

Multiply -4 by x to get: -4x

Muliply -4 by -2 to get: 8 (Because two negatives make a positive)

Now you have -4x + 8

Rewrite so it flows better and the answer is:

8 - 4x
