Here’s why:
- A trinomial is a expression that consists of three terms.
- A term can be a number, variable, or both numbers and variables that are multiplied together.
- Answer choice 'D' has three terms, c², 'c', and '6'. Therefore, it is a trinomial.

Hope this helps you. I apologize if it’s incorrect.
John made $40 commissions for $500 sales or 40/500. He wants $320 for an unknown amount of sales or 320/x.
40/500=320/x Cross multiply.
40x=160,000
Divide both sides by 40.
X=4,000
He needs his sales to be $4,000 to get $320 in commission.
