Please help! What’s the error in line 1 ?

sveticcg [70]

Answer:

When you add variables with exponents, you do not add the exponents together.

The error -> $y^2+2y^2=3y^4$

In this case, they have added the exponent $2+2=4$ .

However, you do not add it. Instead, the answer should be $3y^2$

Dafna1 [17]

Answer:

A

Step-by-step explanation:

All other options are more biased

In B, the official wants to use 50 people from a library to represent the <u>entire town's</u> opinion on the library itself.... that's biased.

In C, it's the same. Of course basketball players would like to watch basketball.... right?? That's why the choice is biased.

In D, the location is a deli.... and from experience people order meat at a deli... cuz why else go there?
