Answer:
D
Step-by-step explanation:
correct
Answer:
r≤9
Step-by-step explanation:
Answer:
x+74=180
x=180-74
x=106
x=4y+22
106-22=4y
84/4=y
21=y
y=21
Step-by-step explanation:
I am fairly certain it is C
Minus 14 from both sides
x²-4x-14=0
use quadratic formula because we cant factor
for
ax²+bx+c=0

so
1x²-4x-14=0
a=1
b=-4
c=-14





the solutions are
x=2+√3 and
x=2-√3
