6- -2n=3n -(6+5) lol sry i actually just need a little push on this question

-6- -2n=3n -(6+5)

-6 +2n = 3n -11

subtract 2n from each side

-6 = n-11

add 11 to each side

-6 +11 = n

5 =n

step-by-step explanation:

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
