Answer: fg(x) = 16x² + 32x
Method:
First you must substitute g(x) into f(x).
Where the x is in the equation f(x) substitute the equation of g(x).
So it should be fg(x) = (x4)²+ 8(x4).
Then simplify the equation to
fg(x) = 16x² + 32x

Answer:
<h2>A, B, D, E</h2>
Step-by-step explanation:
2(2x + 1) = (2)(2x) + (2)(1) = 4x + 2 → A
<em>used distributive property</em>
2(2x + 1) = 2(1 + 2x) → B
<em>used commutative property</em>
2(2x + 1) = (2x + 1) + (2x + 1) = 2x + 1 + 2x + 1 → D
<em>used 2a = a + a</em>
2(2x + 1) = 4x + 2 = x + x + x + x + 1 + 1 → E
<em>used 4x = x + x + x + x and 2 = 1 + 1</em>
