This is also with the other one sorry I just don't get it: -8x = -64
50 = -(1/8)p
-90 = 8 + y
if someone can help me please help me.

x = 8

p = -400

y = -98

Step-by-step explanation

-8x = -64

Divide both sides by -8

x = 8

50 = -(1/8)p

Divide both sides by -(1/8)

p = 50/-(1/8)

p = -400

-90 = 8+y

Subtract 8 from each side

y = -98

the answer is 489

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
