first off let's recall that a square has all equal sides, so its area is just one side squared, namely A = s², or A = (s)(s).
we know the area is 16j² + 24j + 9, that simply means that two twin factors are in it, and it also means that the area polynomial is a perfect square trinomial.
The first one. if you use one of the points to substitute the variables, you’ll see that the equation is true
By computing x=3600 * 1/ 57.1= 63.047 miles per hour
