100$ because the income you have to earn is 400$, right? If so then 100 * 4 give you 400.
1) When the denominator equals zero that is a critical point
=> x - 2 = 0 => x = 2.
So x = 2 is a critical point
2) Simplify the numerator to find an expresion of the king p(x) ≥ 0 or p(x) ≤ 0. Where p(x) equals zero you have other(s) critical point(s)
Multiply both terms:
[2x + 5] / [ x - 2] = [x - 1] / [x - 2]
for x ≠ 2 => 2x + 5 = x - 1
=> 2x - x = - 1 - 5
=> x = - 6
Then, the two critical points are x = 2 and x = - 6.
Answer: option B.
Answer:
The answer is 
Step-by-step explanation:
We have to:

So, if we take the 60 degree angle of the smallest triangle, we have to:

We do not know x. But if we take the sine of the angle of 30 degrees and the main triangle we have:

Then:



Answer:
x = 34/13
Step-by-step explanation:
3(5x - 6) + 2(x + 8)
15x - 18 = 2x + 16
15x = 2x + 34
13x = 34
x = 34/13
Best of Luck!
