The binomial (x+2) is a factor of ? 1). 2x^{2} -5+3
2). x^{2} +5x+18
3). x^{3} +5x^{2} + 18
4). x^{3} +5x+18

4).

Step-by-step explanation:

The binomial (x+2) is a factor of

Since, (x + 2) is a factor.

So, x = - 2 is a root

Plug x = - 2 in

We find:

Since, at x = - 2 the value of the expression becomes zero.

Therefore, (x + 2) is a factor of

answer: 15

step-by-step explanation:

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.
