find the number of miles per 1 liter:
247 kilometers / 19 liters = 13 kilometers per liter.
Divide how may kilometers they want to go by kilometers per liter:
429 kilometers / 13 kilometers per liter = 33 liters are needed.
Answer:
169
Step-by-step explanation:
x−2=13
First find the value of x
x-2+2 = 13+2
x = 15
Now substitute into the expression
x^2 -4x+4
15^2 -4*15+4
225 - 60+4
165+4
169
