Answer:
- 2 and 7
Step-by-step explanation:
A polynomial P(x) divided by (x + h) has remainder f(- h) ← remainder theorem
P(x) divided by (x + 5) has remainder P(- 5) = - 2 ( from result given )
P(x) divided by (x - 3) has remainder P(3) = 7 ( from result given )
5a - 4a = -9 - 8a
a = -9 - 8a
9a = -9
a = -1
The centroid is 1/3 the distance from any side to the opposite vertex (along the median). That is, the centroid divides the median into parts with the ratio (1/3):(2/3) = 1:2. Then QE = (1/2)AQ, so
... QE = (1/2)·18 = 9 . . . . matches selection C.
