Discriminant = b^2 - 4ac, where a, b and c come from the form of the quadratic equation as ax^2 + bx + c
Discriminant = (4)^2 - 4(1)(5)
= 16 - 20
= -4
-4 < 0, therefor there are no roots
(If the discriminant = 0, then there is one root
If the discriminant > 0, there are two roots, and if it is a perfect square (eg. 4, 9, 16, etc.) then there are two rational roots
If the discriminant < 0, there are no roots)
19 feet
convert 2 
into an improper fraction
2 = 
hence the length of the wall is 19 feet
Answer:
26/3
Step-by-step explanation:
First, you need to turn the fractions from mixed form to improper fractions.
3 1/4 x 2 2/3
13/4 x 8/3
13/4 x 8/3
= 26/3
