I'm assuming that you meant:
y = 7x² + 3
Remember! Inputs are always x values (unless stated otherwise). Meaning the problem says:
x = 4
y = 7(4)² + 3
The square only applies to the 4. The 7 is not going to be squared! (To be exact it only applies to whatever the value of x is.
4² = 4·4 = 16
Remember:
Parenthesis
Exponents
Multiplication
Division
Addition
Subtraction
Follow PEMDAS from left to right (or in the case above from top to bottom).
7·16 + 3 = ?
16·7 = 10·7 + 6·7 = 70 + 42 = 112
(All I did to multiply was break it up into parts. If it confuses you don't worry about it, and just multiply it out like normal or use a calculator if you are allowed to)
112 + 3 = ?
Our output is:
115!
The answer would need 8 gallons.
it will normally not come to some one but i believe that you can not just get 1/2 of a gallon you can use 1/2 of a gallon so you need to round up even if the number should round down i needs to be rounded up since you can't have to less to travel a certain distance but you can have to much. so it is 8 gallons of gas
hope it helped
Total volume

9/2
volume of 1 cup
3/4
how many cups can be made
(9/2) / (3/4)
(9*4) / (2*3)

You should try starting a conversation with him if you're in the same class/have a class together you can ask how he's liking the class. Don't straight up ask to be his friend that might make him confused. Work on it a little each day maybe even try to compliment him a few times. I hope this helpsss
