The answer is D. 42
A triangle equals 180 in total so what you would do it subtract 122 from 180 because 180 is also the angle of a straight line. You would get 58 then you add 58 and 80 to get 138. Subtract 138 from 180 and you get your answer of 42
Rise over run = y2 - y1 / x2 - x1
3-12/-8 - (-17)
-9/ 9 which simplifies to —> -1 = slope
Paula would be 14 times 6 or 84
Tina would be 13 times 8 or 104
So tina made more
Answer: -2(f + 5)
Explanation:
5a+2a(5−b)
Distribute:
=5a+(2a)(5)+(2a)(−b)
=5a+10a+−2ab
Combine Like Terms:
=5a+10a+−2ab
=(−2ab)+(5a+10a)
=−2ab+15a
