Answer:
The answer to your question is the letter D.
Step-by-step explanation:
Equation
(x + 5)/(x² + 7x + 10) = (x - 4)/ (x² - 2x - 8)
Process
1.- Factor both denominators
x² + 7x + 10 = (x + 5)(x + 2)
x² - 2x - 8 = (x - 4)(x + 2)
2.- Substitute
(x + 5) / (x + 5)(x + 2) = (x - 4)/(x - 4)(x - 2)
3.- Simplify
1/(x + 2) = 1/(x - 2)
4.- Solve for x (cross multiplication)
x - 2 = x + 2
x - x = 2 + 2
0 = 4
5.- Conclusion
The solution is all real numbers except -5, -2 and 4.
Answer:
I'm guessing that when you graph it, the graph changes direction when it's not on the x-axis. the "real zeros" of a graph are the ones that go through the x-axis and then imaginary ones are the ones that don't.

Answer:
151.5
Step-by-step explanation:
the ratios of the sides PQ:ST=4:3, and the perimeter of POQ is 202, so 3/4 of 202 is 151.5
