Pls helppp i have a timer!!
(10 points)

they are both corresponding angles (equal)

48=4x

48/4=x

12=x

x = 12

Step-by-step explanation:

4x and 48 are corresponding angles and are congruent, then

4x = 48 ( divide both sides by 4 )

x = 12

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)
