  1. A
    3. A
    2 times x is 2x, 2 times y is 2y; therefore it is 2y +2x
    2 times 3x is 6x, there is no possible way for the answer to be 5x
Cortes33

if you multiply the outside number by all the terms in the parenthesis you'll get;
2(x + y) = 2(x) + 2(y)= 2x + 2y giving you A as your answer in Q.#2.
And for Q.#3 the its the same steps;
2(3x) = 2(3)(x) = 6x Giving you A as your answer cause; 5x is not equivalent and the others are equivalent to 6x by multiplying as I explained you.
hope that helps :D
