Solve for p: 5−p+6 = 8

p=3

Step-by-step explanation:

To solve, we need to isolate the variable: p

5−p+6 = 8

Combine like terms

5+6 -p =8

11 -p=8

Subtract 11 from both sides

-p = -3

Divide both sides by -1

p=3

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

b.   e = 7.5h

hope this , lovely!
