Answer:
x = - 1
Step-by-step explanation:
Given
4x = x^2 - 5 Transfer 4x to the right side.
Solution
x^2 - 4x - 5 = 0 Factor
(x - 5)(x + 1)
You want the negative solution. That means that the middle sign must be plus.
x + 1 = 0 Subtract 10 from both sides
x = - 1 Ten on the left disappears by the subtraction process.
Is that correct?
4x = x^2 - 5
x = - 10
4*(-1) = (-1)^2 - 5
-4 = ? 1 - 5
-4 = - 4
and it does work.

Answer:
3,000
Step-by-step explanation:
Basically, there are 300 seats filled which is 10%
100% is 10x10
300=10%
multiply both sides by 10
300x10=3000 and 10x10=100
therefore, the total number of seats is 3000 since 100% represents the whole thing.
