Answer:
64 Maybe
Step-by-step explanation:
Hi Kristian
a - 3b = 22
a = b - 2
We need to solve a = b -2 for a
First, we need to substitute b - 2 for a in a - 3b = 22
a - 3b = 22
b - 2 - 3b = 22
-2b - 2 = 22
-2b = 22 + 2
-2b = 24
b = 24/-2
b = -12
Now substitute -12 for b in a = b - 2
a = b -2
a= -12 - 2
a= -14
Thus, the solution is a = -14 and b = -12
The correct option is the last one (-14,-12)
If you have questions about my answer, please let me know.
Good luck!

Solution:
Given:
Using the trigonometric ratio of cosine,
Therefore, OPTION A is correct.
Two segments that are tangent to a circle from the same external point are of equal length.
9) 2x²=8x
2x²-8x=0
x(2x-8)=0
x=0,
2x-8=0
x=4 can be
2*4²=8*4=32
10) y=y²/7
y²/7- y=0
y(y/7 -1)=0
y=0,
y/7 - 1=0
y/7=1
y=7 can be
y=y²/7= 7
