What does x =

-7 is your answer

Step-by-step explanation:

hope it helps

-7

Step-by-step explanation:

5x = -35

x = -35/5

x = -7

to find x, all I did was take 5 to the other side, so when it was on the left side, it was being multiplied. But when taken to the right side, it goes to the opposite, so the opposite of multiplication is division.

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
