Explanation:To get the value of k, we will need to isolate it on one side of the equation.
This can be done as follows:
d = a(2+kt)
<u><em>1- get rid of the brackets using distributive property:</em></u>
d = a(2+kt)
d = 2a + akt
<u><em>2- Subtract 2a from both sides of the equation:</em></u>
d - 2a = 2a + akt - 2a
d - 2a = akt
<u><em>3- Divide both sides of the equation by "at":</em></u>
