Answer:
D) x² -x - 10 =0
Step-by-step explanation:
Given that
L.C.M
⇒ 
⇒ 9 x + 54 = 9 x² - 36
⇒ 9 x² - 36 - 9x - 54 =0
⇒ 9 x² - 9x - 90 =0
⇒ 9(x² -x - 10 ) =0
⇒ x² -x - 10 =0

Answer:
a. (5x+75)°
b. x = 21
c. X° = 21° and (4x+75)°= 159°
Step-by-step explanation:
A. Combine like integers.
B. (5x+75)°=180° Because they are suplementary angles.
5x°= 105°
5x ÷5 = 105 ÷ 5
x = 21
C. (4x + 75)°
4(21) + 75
84 + 75 = 159°
