A teacher wants to demonstrate to her students, so she plans to cut a plece of wood exactly 2n feet in length and show it to them. Explain why
she cannot do this. Then give an approximation for how long the piece of
wood should be. .NS.2
Explanation:
approximate Length:

A) for the n row: 22+(n-1)×6therefore,b) 100-22=78that means (n-1)×6=7878÷6=1313+1=1414th row has 100 seats

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.

Oh i'm sorry. didn't see the options
