Answer:
2 Real Roots
Step-by-step explanation:
The discriminant (D) is found using the formula b^2+4ac for the equation ax^2+bx+c.
If D>0 there are two real roots, D=0 one real root and D<0 no real roots.
D = b^2+4ac
D = 10^2+4(-4)(-8)
D = 100+32*4
D = 100+128
D = 228
since 228>0
There are 2 real roots
The person whose walk is longer is Erica.
Erica's walk is 8/9 times longer than Erica's walk.
<h3>Whose walks the longer distance?</h3>
In order to determine who walked the longer distance, we would convert the fractions to percentages.
3/4 becomes 75%
2/3 becomes 66.7%
Erica's percentage is smaller, thus, she walks a longer distance.
Jordan's walk is 8/9 times longer
(2/3 ÷3/4) (2/3 x 4/3 = 8/9)
