8/2 is 4 and -10 + -2 is -12 because your adding two negatives
Answer:-y,x
Step-by-step explanation: It is rotateing into the negative part of a graph if you think about it.
180-(83+53)=44
That will be the answer
diameter (d) = 2 · r
Circumference (C) = 2 π · r → C = π · d → d = 
Answer:
see explanation
Step-by-step explanation:
(b)
30n - 12 ( factor out the gcf 6 from each term )
= 6(5n - 2) ← in factored form
(c)
6x + 9y ( factor out the gcf 3 from each term )
= 3(2x + 3y) ← in factored form
