Simplify 10(N + 3).<br><br> 10N + 30<br> 10N + 13<br> 10N + 3
Alika [10]
N+3 evaluates to N+3
Multiply 10 by N+3

Multiply 10 by each term in N+3 term by term.

This is the distributive property of multiplication.

Multiply 10 and N
Multiply 1 and N

The N just gets copied along.
10 × N = 10N

Multiply 10 and 3
10 × 3 = 30

10*(N+3) evaluates to 10N+30

***The final answer is 10N+30***
