It's the first one, an algebraic expression contains variables
Answer: acute
Step-by-step explanation: it is less than 90 degrees so it is less the right angle
13/17 is at the lowest because they are both prime numbers.
Answer:
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
