4(60q-190u-13b+17i) you have to factor the polynomials
(f-g)(x) = x²+6x - (7-x)
(f-g)(x) = x² + 6x - 7 + x
(f-g)(x) = x² + 7x - 7
(f-g)(9) = 9² + 7*9 - 7
(f-g)(9) = 81 + 63 - 7
(f-g)(9) = 137
Answer: 10
Step-by-step explanation:
My answer is correct because, if x=5 then were just multiplying 2 times 5 since 5 is not on the top like because if it was that means we have to multiply 2 by itself 5 times. But since its not a exponent you just multiply 2 times 5. And 2 x 5= 10.
Hope This Helps!
