The denominator would still be the same you placed the marble back into the bag
X= -5/8-5/8√33 or x= -5/8+5/8 √<span>33</span>

Time taken for Kristin to catch up with the truck will be found using the formula
time=(distance)/(speed)

Pythagorean Theorem: a^2+b^2=c^2
(9)^2 + b^2 = (23)^2
81 + b^2 = 529
b^2 = 529 - 81
b^2 = 448
b^2 =
b = 21.2
