Answer=D

10x^2-14x

Step-by-step explanation:

Using the distributive property, you are going to multiple 2x by everything. First 2x times 5x. We know that 2 x 5 is 10 and when you multiply 2 x's then it will be x^2. So the first part is 10x^2. The second thing you're multiplying is 2x times -7. Do not forget the negative sign! You will do -7 times 2 to get 14 and then add an x to the end because 1 times x = x. As the final answer you are going to get 10x^2-14x when you put it all together.
