Answer:
Option C. negative
Step-by-step explanation:
we know that
In a quadratic equation of the form
The discriminant is equal to
If D=0 ----> then the system has only one real solution
If D > 0 ---> the the system has two real solutions
If D < 0 ---> then the system has complex solutions
The quadratic equation of the graph has complex solutions
therefore
The discriminant is negative
Answer:
6
Step-by-step ex planation :
third side = x
8 ² + x ² = 10 ²
64 +x ² = 100

Answer:
Yes
Step-by-step explanation:
Pythagorean theorem states that for right triangles a^2 + b^2 = c^2, which is true for this as a^2 = 1225 + 144 (b^2) = 1369,
1369 = 37^2
Step-by-step explanation:
=(-2)2+8(-2)+18(-2)+12
=4-16-36+12
=4+52+12
=56+12
=68
OR
=4-16-36+12
= -12-24
= -36
