Question

Use properties of operation to determine whether 5(n + 1) + 2n and 7n + 1 are equivalent expressions.

Answer 1

No. No Solution

Explanation:

5(n + 1) + 2n --> 5n + 5 + 2n -->7n + 5

7n + 5 ≠ 7n + 1

Answer 2

Not equivalent.

Explanation:

5(n + 1) + 2n

Using the Distributive Law:

= 5n + 5 + 2n

= 7n + 5.

The other expression is 7n + 1 so they are not equivalent.
