The answer would be C

Explain? please

Answer 3

Since 2a is multiplied by all of the other parts of the equation, the answer would be (2a x 5a2) + (2a x 3a) + (2a x -17)

Answer 4

2a x 5a^2 is 10a^3 since whenever you multiply variables together.
For example, this can be thought of as 2 x a x 5 x a x a
Same concept for the others
