Equation: a^2 + b^2 = c^2
18^2 + 16^2 = c^2
324 + 256 = c^2
C^2 = square root 580
Square root 580 reduces to 2 square root 145.
As a decimal that is: 24.08
Rounded to the nearest tenth: 24 inches.
I hope this helps! If it does please offer me the brainiest!

$10 because 2 and 3 add together and subtract 15 equals 10
300miles/20sec=?miles/1min
900miles/60sec=?miles/1min
900miles/1min=?miles/min
?=900 miles
