(f+g-k)(x) means to add the equations f(x) and g(x) then subtract k(x)
2x^2 + 3x + 4x - 9 = 2x^2 +7x -9
2x^2 + 7x - 9 - x^2 -7x = x^2 -9
The answer is : x^2 - 9
Answer:
all real number

A ratio that is equivalent is 18:48
Answer:
n = 5
Step-by-step explanation:
1) Use power rule:
.

2) Cancel the base of z on both sides.
2n = 10
3) Divide both sides by 2.

4) Simplify
to 5.
n = 5
