Garret is partway through a 20-minute bike ride. It takes 4 minutes for him to go a kilometer. Suppose k is the number of kilometers Garret has already biked. The expression 4(5-k) describes the number of minutes Garret has left in his ride.

The way it is right now looks good.

Step-by-step explanation:

if it takes him 4 minutes to go one kilometer then the equation 4(5-k) which is minutes left is saying how many kilometers out of the total 5 are left multiplied  by the amount of time it takes to go one kilometer  

when studying polynomials, you often hear the terms zeros, roots, factors and x x the multiplicity of a zero is important because it tells us how the graph of the let's look at the graph of a function that has the same zeros
