Answer:
(f+g)(x) = x^2 +10x +7
Step-by-step explanation:
(f+g)(x) = f(x) +g(x) = (15x +7) +(x^2 -5x)
= x^2 +x(15 -5) +7
= x^2 +10x +7
First, multiply 5 • x, which is 5x. Then, multiply 5 • 1, which is 5. Now you have the equation 5x + 5 = -20. Now, subtract 5 from +5 and do the same to the -20, which gets you -25. Now divide -25 by 5, which is -5. Therefor, x= -5. Check by multiplying -5 • 5, which is -25. Then add -25 + 5, which is 20 and you now know your answer is correct.
Final Answer: x = -5
