8+1 +12-3
9+9
The answer should be 18
It’s an expression. there is no like terms within the expression so it remains the same. each variable is different because of either the “a, b, x, y” or the squared.
Answer:
B'C'D'
Step-by-step explanation:
The figure was just translated, without any deformation, these are similar figures... so their corresponding angles are the same.
Since it was just moved down by 4 units, none of the angles were changed, and none of the side lengths were changed.
Since vertex C' corresponds to vertex C, the angle B'C'D' corresponds to original angle BCD.
