(15x - 2) + (7x + 4) = 90
x = 4
The answer is A I am pretty sure. This is because in choice B, you would be dividing 7 and the sum of x + 5. In choice C you would not be multiplying 7 and the sum of x + 5. When he question asks for the product, it is asking for you to multiply. In choice D you would not just be squaring y, you would be squaring 2xy, which is not what we want. We only want to square y, therefore I believe the correct answer is A.
