Will give brainliest to first answer! what common angle do triangle ace and triangle ebc share? a. afb is congruent to efd b. ace is congruent to ecb c. ebc is congruent to ecb d. cad is congruent to ceb

The first one is correct because the angle on the opposite side is the same, and the second one is correct too because it's the same points.  So you can pick either or.

Step-by-step explanation:

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1
