Answer:
-2a²
Step-by-step explanation:
The question is 2a × -a
This means 2a(-a)
= -2×(a×a)
=-2(a²)
=-2a²
The second option. Angles 2 and 6 are corresponding angles, and 6 and 7 make a linear pair, so 2 and 7 are supplementary.
The first option doesn’t even mention angle 7, the third option doesn’t mention angle 2, and the last option doesn’t mention 7 either.
6/20 chance or simplified would be 3/10. Answer [D] is correct.
