Answer:
-16x+14y-45z
Step-by-step explanation:
4x+4y-5(4x-2y+9z)
we apply the distributive property:
4x+4y-5*4x-5*(-2y)-5*9z
so we have:
4x+4y-20x+10y-45z
-16x+14y-45z

Answer:
4x - 36 feet
Step-by-step explanation:
The area A of a square whose sides are s units is given as
A = s * s
Given that the area A = x^2-18x+81, factorizing
A = x^2-9x-9x+81
A= x(x-9)-9(x-9)
A = (x-9)(x-9)
A = (x-9)^2
This means that the size of each side of the square courtyard is x-9 feet long
Recall that the perimeter P of a square whose side is s long is given as
P = 4s hence since the side of the courtyard is x - 9 feet, the perimeter of the courtyard
P = 4(x-9)
= 4x - 36 feet
K to the 6th power, because you can add k to k to the 5th power to make k to the 6th, and n to the 5th and n to the -5th cancel each other out.
