Use the Remainder Theorem to determine which binomial is a factor of the function f(x) = x^3 − 19x + 30.

A. (x + 2)
B. (x + 3)
C. (x + 5)
D. (x − 5)

Hey There!

In order to solve this you need to factor f(x) = x^3 - 19x + 30 Entirely.

When you do that you get these factors;

f(x) = (x – 2) (x – 3) (x + 5)

From there you play 'elimination'

A) There is no listed factor for (x + 2)

B) There is no listed factor for (x + 3)

C) There is a listed factor for (x + 5)!

D) There is no listed factor for (x - 5)

yo answer should be 6 if im not mistaken

step-by-step explanation:

m∠cdf = 43° , m∠gdf = 114°, m∠gde = 23°, m∠edh = 23° , m∠cdh = 157°

step-by-step explanation:

since, it is given that de bisects the angle gdh ⇒ de divides the angle gdh into two equal angles.

⇒ m∠gde = m∠edh

⇒ 8·x   - 1 = 6·x + 5

⇒ x = 3

so, m∠gde = 8·x - 1 = 23°

and m∠edh = 23°

now, it is given ∠cde is an straight angle so, m∠cde = 180°

⇒ m∠cdf + m∠fdg + m∠gde = 180°

⇒ 43° + m∠fdg + 23° = 180°

⇒ m∠fdg = 114°

again, m∠cde = m∠cdh + m∠edh = 180°

m∠cdh + 23° = 180°

⇒ m∠cdh = 157°
