Pls help me. I will mark you as if you help me get the correct answer.

C and D

Step-by-step explanation:

Let's add this all together.

9x + 5y + x - 3y

Combine like terms 5y + -3y and 9x + x

10x + 2y

So we know D is at least correct.

What else? C is also correct, because we can expand it outward.

10x + 5y - 3y = 10x + 2y

A and B are not correct! We can't multiply the ys or the xs.

i do not know this sorry : (

costs the what? what is the cost of the pants?

step-by-step explanation:

if it is $10, then the price is 14.

take 40% of the cost, and then add the cost.

40% of 10 = 4

4+10 = 14.
