Which value of x makes the following equation true? 5 x + 3 x = 72 x

I might be wrong

Step-by-step explanation:

x= 9? sorry if that's wrong

x =9

Step-by-step explanation:

take off the x

add 5+3=8

divide 72 by 8

answer is 9 so x=9

you can double check by multiplying 5×9 then 3×9 then adding your answers together to give you 72

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

the answers might not be correct use at own risk
