Answer:
Do you see the lines and how they are named? I am going to try and explain this in less words than I can. Where it says XS you have to match it up with the lines. But if it says that you have to find XSU (which it does not) you would have to go up all the way but you stop where it says the S so you wont go all the way up to the U. I hope this helps!
X^2-5x, given x=7,
(7)^2-5(7)=14
sqrt(14)=3.74
The number with the same value will be 40 because 10 tens make 100 and 4 tens make 40 so it wili be 140
