This will give us:

Answer:
- 2x² + 3x + 64
Step-by-step explanation:
3x - (2x-8)² Write the equation and distribute the exponent
3x - 2x² + 64 Write the equation in order of degree of exponents, or standard form
- 2x² + 3x + 64
In the picture with the triangles Phillip is correct because the triangle does not give the measurements of the same side so there is no proof of any sides to be the same. With the other picture what I did was I reversed the translation which got the points A (-2,1) B (-5,3) Then I reversed the rotation which got me A(2,-1) and B (5,-3). So line AB endpoints would be located A (2,-1) and B (5,-3).
Hope this helps!
