What number should both sides of the following equation be multiplied by in order to solve for x?

x/7.25= 4

4
7.25
7
29

7.25

Step-by-step explanation:

Multiplying both sides of this equation by 7.25 will both eliminate the fraction and isolate (solve for) x;

7.25(x/7.25= 4) → x = 4(7.25)

                             x = 29

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
