Hello from MrBillDoesMath!
Answer:
m^2 + 11m - 11, which is the first choice
Discussion:
6m + (m-2)(m+7) +3 =
6m + (m^2 + 7m - 2m -14) + 3 =
(6m + 7m - 2m) + m^2 + (-14 + 3) = combine similar terms
11m + m^2 -11 =
m^2 + 11m - 11
which is the first choice
Thank you,
MrB
Find the measure of the third angle
Use your trig functions the get the sides
Then calculate area and perimeter
Mean Absolute Deviation I'm pretty sure. Hope this helped, have a great day! :D
3+-4=-1
3-4=-1
-1=-1
so the answer is:
-1 = -1
