Answer:
D
Step-by-step explanation:
Given
x³ + 2x² + 7x + 14 ( factor the first/second and third/fourth terms )
= x²(x + 2) + 7(x + 2) ← factor out (x + 2) from each term
= (x² + 7)(x + 2) → D

The Y-intercept is a point where the line crosses the Y lines. That means it would be the point where X=0. Then to find the Y-intercept you only need to insert X=0 into the equation. The calculation would be:
<span> 4×+2y=12
4(0) + 2 Y= 12
2Y =12
Y=6</span>
Answer:
a = 4/27 - b/54
Step-by-step explanation:
27a+1/2b=4
Subtract 1/2 b from each side
27a+1/2b - 1/2 b=4-1/2 b
27a = 4 - 1/2 b
Divide each side by 27
27a/27 = 4/27 - 1/2 b/27
a = 4/27 - b/54
