The answer is 81 I think, I would suggest you to type in the calculator 4 • 18+9
Answer:
B. The consecutive angles are supplementary
Answer:
The answer is D. 14
Step-by-step explanation:
If you were to plug in 14 for x, it would look something like this:
= 
Solve 14-4
= 
if you were to multiply 5 and 7 by 2, you would get
.
This makes the equation true, because
10/14 does equal itself (10/14)
Have a nice day!
Answer:
(-9, 10)
Step-by-step explanation:
The location of the midpoint of a line with endpoint at (
) and (
) is given as (x, y). The location of x and y are:

Given the endpoint (9,8) and Midpoint (0,9), the location of the other endpoint can be gotten from:

Hence the endpoint is at (x2, y2) which is at (-9, 10)
