Answer:
b. not similar
Step-by-step explanation:
The given sides* have the ratio 30:39 = 10:13 in one triangle and the ratio 20:27 = 10:13.5 in the other triangle. Since these ratios are different, the triangles cannot be similar.
____
* These are the sides bracketing the vertical angles at T. If the triangles were similar, the three sides would have to have the ratios 10 : 13 : 13.5.
However, the geometry shown would require that the angle opposite side 13.5 in one triangle have the same measure as the angle opposite side 13 in the other triangle. That is not possible, so it is not possible for these triangles to be similar.

Answer:
Yes, Sierra is correct
Step-by-step explanation:
Given

Is she correct
The right parenthesis has 4 + 5.
This can be simplified as: 
So, we have:
The left parenthesis has y + 7.
This cannot be simplified because y is a variable and 7 is a number.
<em>Hence, Sierra is correct.</em>
Answer:
I think is is 5.4
Step-by-step explanation:
what I did is divided the problem
It’s letter C.
If you start at point (0,0) and go up two over one (rise over run) to the left, you’ll be at (-1,2). Go up two over one again to the left to get to (-2,4). Your equation would be: y=-2x+0 (0 because you started at 0 so your y-intercept is 0) though since it’s +0 you can leave that out and have y=-2x. It’s a negative slope because the line would be going down to the right.
