Alana is writing a coordinate proof to show that the diagonals of a rectangle are congruent. She starts by assigning coordinates
to a rectangle as shown. Then she uses the coordinates to write and simplify expressions for the lengths of the diagonals.
What is the length of one of the diagonals of the rectangle?
Enter an expression in the box for the length of the diagonal.

It is provided that
We need to determine t when d equals 74
Thus, or
t(16t + 37) - 2(16t + 37) = 0
(t - 2)(16t + 37) = 0
t - 2 = 0 or 16t + 37 = 0
t cannot be negative.
Thus, t equals 2
Therefore, it will require 2 seconds for the object to cover 74 feet.
