Question

Fan and medal halp plz

Answer 1

Given f(x) = 3x − 10 and g(x) = 12x + 8, solve for (f + g)(x) and select the correct answer below.

(f + g)(x) = 15x − 2
(f + g)(x) = 9x − 2
(f + g)(x) = 15x + 2
(f + g)(x) = 36x2 − 120x

Answer 2

So you have to multiply 12x+8 and 3x-10

Answer 3

ok ;^)

Answer 4

So it is a binomial so what is 12x times 3x?

Answer 5

36

Answer 6

yes but don't forget to combine like terms with the x. So 36x^2. Now what is 3x * 8?

Answer 7

its 24 and ok

Answer 8

Hold on I looked at it wrong

Answer 9

The notation, \((f + g)(x)\) is equal to \(f(x) + g(x))\).

Answer 10

Yes @Algorithmic is right so what is 12x + 3x?

Answer 11

addition now? Ok 15x?

Answer 12

yes and what is 8-10?

Answer 13

-2

Answer 14

Good job and when you combine them it is (f + g)(x) = 15x − 2. So which answer do you think it is A, B, C, or D?

Answer 15

A

Answer 16

Thank you very much to everyone I wish I could medal you all :P

Answer 17

No problem and you are right it is A.
