Multiply -2 at both sides
d-10=-14
d=-14+10=-4
The answer is -4
x^2 + 5x = -2
x^2 + 5x + 2 = 0
We need to use the quadratic formula.
In the formula, a = 1, b = 5 and c = 2.
See picture for quadratic formula. Plug in the value for a, b, and c into the formula and do the math.

X=83. This is because all of the answers combined (excluding 2x) is 664. there are a total of 6 exterior angles. now you take the 6 total angles + 2x. which is 8x. here is your equation. 8x=664. divide each side by 8. x=83.
Multiply both sides by lh, V=wlh
