Step-by-step explanation:
I just used Pythagorean theorem in which c^2=a^2+b^2
so this is c^2= 225 + 196 and then you get c^2= 421 and finally you get the square root of 421 so this way you finally get 20.5 cm

Step-by-step explanation:
cost = 0.78 cents per mile + base fee
y = 0.78x + 15.88
247.65 = 0.78x + 15.88

231.77 = 0.78x
divide by 0.78 on both sides
x = 297.14120256
297 miles
