We can find the distance between two points by using distance formula,

Here,
x₁ = -3
x₂ = 5
y₁ = -2
y₂ = 2
Therefore,

Hence the √80 = 8.94 approx is the distance between the two points (-3,-2) and (5,2).
X + y = 33
x - y = 9 Add the 2 equations together
---------------
2x = 42 Divide both sides by 2
x = 21
Use the original equation and plug 21 in for x, then solve.
x + y = 33
21 + y = 33
Subtract 21 from both sides
y = 12
One list had 21 items on it and the other list had 12 items on it.
