(x + 2) * 5 = 5(x + 2) commutative property of multiplication
5(x + 2) = 5x + 10 distributive property of multiplication over addition
(5x + 10) - 7 = 5x + (10 - 7) associative property of addition
The only listed property that was not used was commutative property of addition.
Answer:
B and D
Step-by-step explanation:
vertical angles are ones that are formed by intersecting lines, and they are also equal to each other and opposite of each other.

B is correct because they are formed by intersecting line and equal to each other
C is incorrect since theres some random line that doesnt completely pass through on either side
D is correct
They are supplementary angles because their sum equals 180 degrees, and they are adjacent because they share a side.
