Answer:
123
Step-by-step explanation:
s=-2
-15s^2-9(-5+s)
=-15s^2+45-9s
=-15s^2-9s+45
=15(-2)^2-9×(-2)+45
=15×4+18+45
=60+18+45
=123

Answer:
(A) Quadrilateral 1 is congruent to quadrilateral 2 because the transformations are rigid.
Step-by-step explanation:
This is because since it's only being reflected across the y-axis and translated 8 units down, it's still an isometric.
Isometry or rigid transformation is the opposite of a non-rigid transformation and occurs during translations, reflections and rotations. Non-rigid transformations occur in dilations.
Isometry basically keeps all measure angles and distances of the polygon the same before and after a transformation.
The sum is 34 and the add and multiemployer
