Answer:
5x less than 300 - 165
Step-by-step explanation:
S=side length
A=s²
121=s²
✓121=✓s²
11=s
Simple ....
we know to find slope is (y1-y2)/(x1-x2)
if we plug in what we know......
(-8,-6),(2,-3)
(-6--3)/(-8-2)
it turns into...
(-6++3)/(-8+-2)
(-3)/(-10)= 3/10
Thus, your answer is that she made no mistake. (C)
I think it is (xy). Hope that is right.
