8y+10
if the fabric = 30 and yards = y then you would put 8(30) + 10 and you would multiply 8 and 30 and get 240.

240 +10
250
Question-
A team math contest has $11$ teams of $6$ students each. Before the contest begins, every student high-fives every other student who is not on their team. How many high-fives take place in all?
Given:
The quadratic equation is:

To find:
The discriminant of the given equation and the number of real solutions.
Solution:
If a quadratic equation is
, then the value of discriminant is:

If D<0, then the quadratic equation has no real roots or two imaginary roots.
If D=0, then the quadratic equation has two equal real roots.
If D>0, then the quadratic equation has two distinct real roots.
We have,

Here,
. So, the discriminant of the given equation is:



Since D<0, therefore the number of real solutions is 0.
Hence, the value of the discriminant is -31 and the number of real solutions is 0.
Answer:
2.13
