Anon25 [30]
Well that's easy it basically tells you all you gotta do is plug in the numbers 

"E" is what you're trying to find out so you don't know that one it stays the same. 

"S" is the amount of money she started with and it says she started with $500 

And then she has $274 less than she started with. 

E = 500 - 274 

E= 226

She is left with $226 after her weekend at the beach.

Which expression can be used to determine the length of segment AB? On a coordinate plane, triangle A B C has points (4, 3), (ne
JulijaS [17]

Answer:

StartRoot 2 squared + 6 squared EndRoot

Step-by-step explanation:

we have

A(4,3) and B(-2,1)

we know that

the formula to calculate the distance between two points is equal to

d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}

substitute the given values

AB=\sqrt{(1-3)^{2}+(-2-4)^{2}}

AB=\sqrt{(-2)^{2}+(-6)^{2}}

AB=\sqrt{40}\ units

therefore

StartRoot 2 squared + 6 squared EndRoot
