Answer:
B. (2a +3b)(4a -c)
Step-by-step explanation:
Group the terms pairwise, then factor each pair.
... (8a² -2ac) +(12ab -3bc)
2a is a common factor in the first pair of terms; 3b is a common factor in the second pair of terms. We can factor those out.
... = 2a(4a -c) +3b(4a -c)
Then we see that (4a-c) is a common factor in the result. We can factor that out.
... = (2a +3b)(4a -c) . . . . matches selection B
Answer:
∠J = 107°
∠K =107°
∠L = 73°
∠M = 73°
Step-by-step explanation:
Angle J + angle M = 180°
(10x - 33) + (4x+17) = 180
simplify:
14x -16 = 180
14x = 196
x = 14
∠J = 10(14) - 33 = 107°
∠M = 4(14) + 17 = 73°
