Answer:
-71 + 22n is the equivalent expression.
This is the simplified expression.
Step-by-step explanation:
4(-11 + 4n) -3(-2n + 9)
= -44 + 16n + 6n - 27
= -44 + 22n - 27
= -71 + 22n

Answer:
x = 24
Step-by-step explanation:
MO is the angle bisector of ∠LMN, thus the following ratios are equal.
= 
, that is
= 
( cross- multiply )
7x = 12 × 14 = 168 ( divide both sides by 4 )
x = 24
Answer:
C. Amplitude = 3 feet; period = 8 hours; midline: y = 4
Step-by-step explanation:
The midline is halfway between the lowest point and the highest point.
y = (1 + 7) / 2
y = 4
The period is the time it takes for a full cycle. So the period is 8 hours.
The amplitude is the distance from the midline to the lowest or highest point.
a = 4 − 1 = 3, or a = 7 − 4 = 3
It's also half the distance between the lowest and highest points.
a = (7 − 1) / 2
a = 3
The range of communication is about 55 meters.
