Answer:
f(x) + g(x) = 2x² - 5x - 8 ⇒ 2nd answer
Step-by-step explanation:
* Lets explain how to solve the problem
- We can add to functions by adding the like terms in them
∵ f(x) = 2x² + 3x - 4
- f(x) is a quadratic function because the greatest power of x is 2
∵ g(x) = -8x - 4
- g(x) is a linear function because the greatest power of x is 1
∵ f(x) + g(x) means (f + g)(x)
∴ f(x) + g(x) = (2x² + 3x - 4) + (-8x - 4)
- Add the like terms
∵ 3x + -8x = -5x
∵ -4 + -4 = -8
∴ f(x) + g(x) = 2x² + -5x + -8
- Remember (+)(-) = (-)
∴ f(x) + g(x) = 2x² - 5x - 8
* f(x) + g(x) = 2x² - 5x - 8
Sum of all angles on one line is 180 degrees.
We have the exterior angle for one angle, so the interior angle = 180 - 136 = 44 degrees.
That angle is the same angle as the one to the right, because those two sides are the same, hence these two angles must be the same.
The sum of all angles in a triangle is 180 degrees. The remaining angle = 180 - 44 - 44 = 92 degrees.
The correct answer is: 44, 44, 92.
