Answer:
AD ≅ BC | Given
AD ║ BC | Given
AC ≅ AC | Reflexive Property
∠DAC ≅ ∠ACB | If 2 || lines are cut by a trans., the | alternate interior ∠s are congruent.
ΔADC ≅ ΔBCA | S.A.S Postulate
BA ≅ DC | Corresponding sides of congruent Δs
So, quad. ABCD is a ║gm | If a quad. has its opposite sides
| congruent, the quad. is a parallelogram.

Answer:
5
Step-by-step explanation:
Distance from B to B' is equal to the distance from A to A', AA'=5 so BB'=5
Answer:
x=6
Step-by-step explanation:
5x+9-3x=21
5x-3x=21-9
2x=12
x=6
Answer:
P ( x ) = (3/5)*[(x-1)^2]*(x)*(x + 1 )
Step-by-step explanation:
P ( x ) = a (x-1)^2(x)^1 (x + 1 )^1
sub P(5)=288
288 = a (4)^2(5) (6)
a = 3/5
