Brian says that the expression 8n + 2 is equal to 83 when n=1. Explain why Brian’s answer is incorrect?

1 answer:

5 0

Answer:

8n+2 first let’s plug in n which is 1

8(1)+2=10

The answer is 10 but Brian said the expression is equal to 83. He is incorrect because 8 times 1 is 8 and then plus 2 is 10.

I hope it helps.
