The answer is A. 60x^3 + 70x^2 + 90x. This is because 10x × 6x^2 = 60x^3, 10x × 7x = 70x^2, and 10x × 9 = 90x. I hope this helps!

Ierofanga [76]

Answer:

x = 4y + 5

Step-by-step explanation:

x represents the total students in the class. We don't know how many teams of four there will be, so we represent that with y. 4y represents the total students in teams of 4. We know there is one team of 5, so that is added to 4y.
