A perfect square is something times that same thing. Example (x+2)(x+2)
The reason it's called a perfect square is because it can be re-written as a squared function:
The answer is 104.
1/4 of 104 is 26, 104 - 26 = 78
78 - 7 = $71
You would just take .5x5 which would be 2.5 inches without the snow melting it would add up to 13.5in the last part with the tt I’m not sure but it follows the same principle .5x(Time)+the original amount will give you the answer
The answer would be A. Commutative property of addition
Answer:
2x^2 + 4x+2
Step-by-step explanation:
f(x) = 2x^2 + x and g(x) = 3x + 2
f(x) + g(x) = 2x^2 + x + 3x + 2
Combine like terms
= 2x^2 + 4x+2
