The answer is going to be 1 because anytime u have a varible by itself you always have to put a one before it. so your fraction would be 1/1+1/1=2/1
Answer:
These triangles are not similar I think
(-10)-3 to the second power is -19 as the answer.
Answer:

Step-by-step explanation:
We are given that the lines passes trough the points (-9, -1) and (0,0).
(0,0) is the origin.
Slope is: 

The slope is one-ninth.
Since the lines passes at the origin, it's y-intercept is 'zero'. We do not write zeros in slope-intercept equations, to the equation of the line should be:

Square root 270 a^2 b^2
3sq root 30 a^2b^
