An outside angle is equal to the two opposite inside angles:

9x -8 = (7x-32) + (5x-27)

Simplify:

9x -8 = 12x - 59

Add 59 to both sides:

9x + 51 = 12x

Subtract 9x from both sides:

3x = 51

Divide both sides by 3:

X = 51/3

x = 17

Now you have X, solve all 3 angles:

7x-32 = 7(17) -32 = 119-32 = 87

5x-27 = 5(17) - 27 = 85-27 = 58

9x -8 = 9(17) -8 = 153-8 = 145

According to the Rational Root Theorem, the following are potential fox) 2x2 +2x 24.roots of -4, -3, 2, 3, 4Which are actual roo

aksik [14]

Correct Answer: First Option

Explanation:

There are two ways to find the actual roots:

a) Either solve the given quadratic equation to find the actual roots

b) Or substitute the value of Possible Rational Roots one by one to find out which satisfies the given equation.

Method a is more convenient and less time consuming, so I'll be solving the given equation by factorization to find its actual roots. To find the actual roots set the given equation equal to zero and solve for x as given below:

$2x^{2} +2x-24=0\\ \\ 2(x^{2} +x-12)=0\\ \\ x^{2} +x-12=0\\ \\ x^{2} +4x-3x-12=0\\ \\ x(x+4)-3(x+4)=0\\ \\ (x-3)(x+4)=0\\ \\ x-3=0, x=3\\ \\ or\\\\x+4=0, x=-4$

This means the actual roots of the given equation are 3 and -4. So first option gives the correct answer.
