Question

Please I really need help

Answer 1

Answer:

$\bold{q(x)=\{5x-12\}+\{-6x-12\}}$

Step-by-step explanation:

Where it says $q(x)=a(x)+b(x)$, it simply means: the answer to $q(x)$ is  adding both functions, $5x-12$ ($a(x)$) and $-8\times2-6x+4$ ($b(x)$).

First, let us solve $a(x)$

$5x-12$

As we can see, this equation cannot be further simplified. So, this is our final result for this problem.

Next, let us solve $b(x)$

$-8\times2-6x+4$

Multiply -8 and 2

-8 × 2 = -16

[remember your integer rules: a negative times a negative is a positive.]

So we have:

$-16-6x+4$

Combine like terms: -16 and 4 are terms that are alike based on them being integers, but -6x id not because it contains a variable. When you combine you are adding.

-16 + 4 = -12

Now we have:

$-6x-12$

As we can see, this equation cannot be further simplified. So, this is our final result for this problem.

Lastly, combine these results.

$q(x)=\{5x-12\}+\{-6x-12\}$

Therefore, that is the answer.
