Step-by-step explanation:
5x^2+10x=5x
Move everything to one side:
=5x^2+10x+(-5x)
Combine like terms:
(5x^2)+(10x+(-5x))
Simplify:
5x^2+5x
95 by 60
perimeter = 310
area = 5,700
A rectangular park that is 100 by 55 has a perimeter of 310 and an area of 5,500.

Answer:1/(8a^12)
Step-by-step explanation:
(2a^4)^-3
2^(-3) x (a^4)^(-3)
1/(2^3) x a^(-12)
1/(2x2x2) x 1/(a^12)
1/8 x 1/a^12
1/(8a^12)
