A. Discriminant =
B. Number of solutions for the quadratic equation =
C. Type of solutions (circle one): Real /Imaginary
D. Type of solutions (circle one): Rational/irrational

A. Discriminant = 116

B. Number of solutions for the quadratic equation = 2

C. Type of solutions (circle one):Imaginary

D. Type of solutions (circle one):irrational

Step-by-step explanation:

The given quadratic equation is

We rewrite in standard form to get;

The discriminant is

where a=1, b=8, c=-13

We substitute to get:

Since the discriminant is great than zero, we have two distinct real roots

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
