Hey there!
x^2 + 4x = 12
SUBTRACT 12 to BOTH SIDES
x^2 + 4x - 12 = 12 - 12
SIMPLIFY IT
x^2 + 4x - 12 = 0
FACTOR the LEFT SIDE of your EQUATION
(x - 2)(x + 6) = 0
• EQUATION #1: x - 2 = 0
OR
• EQUATION #2: x + 6 = 0
SIMPLIFY IT
• EQUATION #1 answer: x = 2
OR
• EQUATION #2 answer: x = -6
OVERALL ANSWER: x = 2 or x = -6
YOUR ANSWER: x = 2 (Option A.)
Good luck on your assignment and enjoy your day!

Answer:
m∠k = 60°
Step-by-step explanation:
- an exterior angle of a triangle is equal to the sum of the opposite interior angles
4x + 2 + 6x - 12 = 130
to find x:
4x + 2 + 6x - 12 = 130
4x + 6x = 130 - 2 + 12
10x = 120
x = 120/10
x = 12
apply the value of x to find the measure of angle K:
k = 6*12 - 12 = 60
