The answer to that is -24a - 6
Answer:
<h2>1) C. 8x + 2x = 10x</h2><h2>2) z = 5</h2><h2>3) y = 10</h2><h2>4) x = 1/2</h2><h2>5) x = 17</h2><h2>6) C. 1/4x + 4 = 3</h2><h2>
Step-by-step explanation:</h2>
<h3>1. <u>C. 8x + 2x = 10x</u></h3><h3 /><h3>2. 3z - 2 = 13</h3><h3>3z = 13 + 2</h3><h3>3z = 15</h3><h3><u>z = 5</u></h3><h3 /><h3>3. -5y - 10 = -60</h3><h3>-5y = -60 + 10</h3><h3>-5y = -50</h3><h3><u>y = 10</u></h3><h3 /><h3>4. 4x - 5 + 2x = -2</h3><h3>4x + 2x = -2 + 5</h3><h3>6x = 3</h3><h3><u>x = 1/2</u></h3><h3 /><h3>5. x - 8/3 = 3</h3><h3>x - 8 = 9</h3><h3>x = 9 + 8</h3><h3><u>x = 17</u></h3><h3 /><h3>6. <u>C. 1/4x + 4 = 3</u></h3><h3>(1/4 × -4/1) + 4 = 3</h3><h3>-1 + 4 = 3</h3><h3 />

(f+g)(x) = f(x) + g(x) = (|x| + 9 ) + (-6) =
|x| + 9 - 6 = |x| + 3
Answer is |x| + 3

Answer: 7(x+3)(x-2)</h3>
========================================
Explanation:
First factor out the GCF 7
7x^2 + 7x - 42
7*x^2 + 7*x + 7*(-6)
7(x^2 + x - 6)
Now focus on factoring x^2+x-6
We need to find two numbers that multiply to -6 and add to 1. Those values are 3 and -2. That means x^2+x-6 factors to (x+3)(x-2).
The 7(x^2 + x - 6) then turns into 7(x+3)(x-2)
The factor out front, the "7", is the integer factor. The other factors (x+3) and (x-2) are binomial factors.
