X = 25
a^2 + b^2 = c^2
19^2 +16^ = c^2
617 = c^2
(Square root 617)
x=24.83
x=25
Marginal profit, P(x) = R(x) - C(x)
P(x) = x³ - 5x² + 7x + 10
x³ - 5x² + 7x + 10 = 0
If you solve it, you get x = -0.839 where P(x) is zero
Answer:

Step-by-step explanation:
So we know that:

To reflect across the <em>y-axis</em>, instead of x, use -x. Therefore:

Simplify:

And that's our answer :)
So what you need to start with is taking the x from both sides as adding 12 to them. Then, you move the 27 over 4 decimals.
