The answer is the third answer choice, I and II only.
This is because both of those motions are rigid since they are just reflections and III is not a rigid motion since it is a dilation, the second triangle is bigger than the first.
Hope this helps!
- - Let's solve for C.
Starting off with our equation:

Transform:

Solve for that:

Solve for that for the last time and your answer is
H(x) equals what? I think you've missed that detail. :)
2x+2=-52
2x=-54
x=-27
That is the simple formula for it.
Isolating s, the equation written in terms of s is:

-------------------------
- The equation for the length of the third side, as stated in the problem,("Maristella uses the equation b = 24 – 2s to find b, the length of the triangle's third side") is:

- To solve for the lengths of the congruent sides, we isolate s, thus:


Inverse of multiplication is division, thus:

Separating into two fractions:
