Option C
Therefore, one of the factors of 
is 
.
Step-by-step explanation:
Given:
the common factor from 
and 
is 4.
therefore, 
Now, use the formula for above expression: 
here, 
and 
Therefore, we have
Therefore, one of the factors of is .
Answer:
A=0.125
B=0.125
Step-by-step explanation
for both you would divide 0.5 by 4. you would cut 0.125 off of each side, but two sides together would 0.25
Answer:
x = 21.4
Step-by-step explanation:
We need to use the law of sins
sin 42 sin x
--------- = ----------
22 12
12 sin 42 = 22 sin x
12 sin 42 /22 = sin x
Taking the inverse sin of each side
sin^-1(12/22 sin 42) = sin^-1(sin x)
21.40637223 =x
To the nearest tenth
x = 21.4
A. If the slopes of two lines are negative then the reciprocals, of the lines are perpendicular.
