Answer:
x^2 + 5x - 14
Step-by-step explanation:
We can assume that if there is 2 options for x, this is a quadratic equation that equals 0.
Therefore, we can put this into brackets as one bracket must equal 0.
(x - 2) (x + 7)
After this we expand, which is a process easier to search up
The answer is:
x^2 + 7x - 2x - 14
We can simplify this to:
x^2 + 5x - 14
x^2 represents x squared in case you were wondering
Therefore, the answer is:
x^2 + 5x - 14
Answer: a). 5
Explanation:
5 > 4
I think is 12??? because area is l×w
Answer
when you place a source of signal at a focal point of an ellipse, the signal will be reflected to the other focal point position
When you place a source of rays as a signal at the focal point of a hyperbola, the ray will be reflected directly away from the other focal point
When you place a source of rays as a signal at one of the parabola focus, the ray will be reflected in lines that are parallel to the axis of the parabola.
