Hello User
To do this we need to first add all of the numbers together.
-18 + -14 + 11 + 13 = -8
The next step is to divide the result by how many pairs of numbers there are.
As you can see there are 4 pairs of numbers
So we divide -8 by 4 to get -2
Therefore -2 is the answer to this problem
I hope I helped :-)

It would be negative six.
If there are equal amounts of blue and green marbles, then there are 56 of each; so 112 altogether. That leaves 28 red and yellow marbles; therefore 14 red marbles.
Answer:
Step-by-step explanation:
Unless we set x^2 + 8x + 15 equal to zero, we don't have an equation to be solved. I will assume that the problem is actually x^2 + 8x + 15 = 0.
The coefficients of this quadratic are {1, 8, 15}, and so the "discriminant" b^2 - 4ac is (8)^2 - 4(1)(15), or 4. Because the discriminant is positive, we know that there are two real, unequal roots.
Continuing with the quadratic formula and knowing that the discriminant is 4, we get:
-8 ± √4 -8 ± 2
x = ---------------- = --------------- , or x = -2 ± 1: x = -3 and x = -5
2 2
