Answer:
A = E and B = D
Step-by-step explanation:
AAS means triangles are congruent if two pairs of corresponding angles and a pair of opposite sides are equal in both triangles. In this, A corresponds to E and B to D. BC and CD are congruent. Therefore the triangles are congruent
y = 3+1/2
that should be the answer
B) 2(3x^2+10x+15
-2b and -0.9b and b/12
