F(x)=-(x+2)^2+3 put in standard form

Hello,

Step-by-step explanation:

do I remind you of the formula  (a+b)²=a²+2ab+b²

Sorry i haven't see the sign minus before the parenthesis.

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )

the first one, all those points on the line just make a strait line.
