To solve this polynomial equation, we first factor the left side.
To factor x² + 8x + 12 = 0, look for factors of 12 that add to 8.
These factors are 6 and 2 so we have (x + 6)(x + 2) = 0.
So either x + 6 = 0 or x + 2 = 0 and solving for
x in each equation, our answer is {-6, -2}.
Answer:
-6
Step-by-step explanation:
For now, let's assume we can rule out choice A.
Angles 3 and 7 are vertical angles. So we can rule out choice B
Angle 3 and angle 11 are corresponding angles. They are on the topside of their adjacent parallel horizontal line. They are also on the left side of the transversal cut line d. The answer is choice C.
Angles 3 and 8 are not corresponding angles. Corresponding angles are not adjacent to one another. In other words, they do not share a common vertex.
Answer:
14.135
Step-by-step explanation:
6 divided by 2 (half) = 3, π·32≈28.27433 dived by 2 (half) equals 14.135
