Answer:

Step-by-step explanation:
We are given quadratic equations as

and it can be factored as

now, we can multiply factor term

now, we can compare

so, we get


we are given that
'a' and 'b' are integers
so, we can find all possible factors


so, we can find k
At
:

we can plug values

So, values of k are

You would basically work backwards and do inverse operations

288/24= 12
A: 38.4 - 25 = 13.4
13.4 + 32.65 = $46.05
B: 50.15 - 32.65 = 17.5
17.5 + 25 = 42.5 mph
