When interpreting expression are (5n)^2 = 5n^2 equivalent?

Expression, E(n) = 5n² + 5n -2

E(-2) = 5(-2)² + 5(-2) - 2

Step-by-step explanation:the answer will be 8

the answer is d

step-by-step explanation:

y+3=-4(x-2)

y+3=-4x+8

  -3         -3  

y=-4x+5

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
