Explain solve for n. 5(n + 4)/3 = n - 8 a)-24 b)24 c)22 d)-22

D.)-22

5(n+4)/3=n-8

5(-22+4)/3=-30

-22-8=-30

-30=-30

answer D.-22

5(n + 4)/3 = n - 8

Multiply through by 3:-

5(n + 4) = 3(n - 8)

5n + 20 = 3n - 24

5n - 3n = -24 - 20

2n = -44

n = -22 (answer)

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
