The correct answer is the first choice :)
First convert both distances to the same unit.
1 mile is 5280 feet or 1760 yards.
Subtract 1760-880 and get 880 yards.
Noah swam 880 yards further than Liam ran.
I think 45 because if you look at the top of the other 45 the graphs look the same lengths except this one stretches out so 45°
Square Perimeter = 4(4x-1)
Rectangle Perimeter = 2(2x+1) + 2(x+2)
Square Perimeter = Rectangle Perimeter
4(4x-1) = 2(2x+1) + 2(x+2)
16x - 4 = 4x + 2 + 2x + 4
16x - 4 = 6x + 6
-6x +4 -6x +4
10x = 10
x = 1
