Answer:
x = ±6
Step-by-step explanation:
x^2/4=9

sqrt(x^2) = ±sqrt(36)
x = ±6
Answer:
the answer is D. 147 degrees
Step-by-step explanation:
114+33=147
check answer by
180-147=33
33+33+114=180
3x-4 = -10
3x-4 +4 = -10 +4
3x = -6
then you can divide it :
x = -6 : 3
x= -2
There are 36 inches in a yard so 36*2.54 = 91.44 centimeters
