1. N + 2; n = 6: the answer is 8 because n=6 so we sub n with that... and we get 6+2 and that’s 8.

2.5f; where f=4: the answer is 20 because when a variable is directly next to a number it is multiplied by that number so we will replace f with 4 and our equation is now 5(4) or 5•4 and both are equivalent to 20.

3. 7b-2; where b=5: the answer is 33 because 7 multiplied by 5(b) minus 2= 7(5)-2 or 7•5-2= 33 because you will multiply 7 by 5 and get 33 then you will subtract by 2 and get 33.

Hope this helps!!!

What is a square root of (a-b)^2

Bess [88]

Hello,

$\sqrt{(a-b)^2}=|a-b| \\ 
= a-b\ if\ a \ \textgreater\ b \\
=b-a\ if\ a\ \textless \ b$
