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

So, values of k are

<span>d = miles from the airport to home.
2.1*d+5=49.10 solve for d
d=</span>49.10-5/2.1 = 21 miles
