Which equation represents the statement: Three times the sum of a number and 5 is –30? 3n + 5 = -30
3(n+5) = -30
n + 15 = -30
(n + 5) ÷ 3 = -30

Step-by-step explanation:

1. Divide the problem into pieces. The sum of a number and five can be written as , where n is any number.

2. Since the question tells us that this sum is multiplied by 3, we expand the expression to .

3. Finally, the question tells us that this expression is equal to -30. This means we can express the entire statement as the equation .

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
