Answer:
4 [ ( x - 5) ( x + 5) ]
Step-by-step explanation:
4x²-100
4 (x²-25)
4 (x²-5²)
4 [( x - 5) ( x + 5)]
Negative 1 because 3 x 3 is 9 and -2 x 5 is -10. Therefore 9-10= negative 1
4n+6=4+2+4n, well first combine like terms, 4n+6=6+4n and those are exactly the same, there's no magical n that can make 4n+6 not equal 4n+6, so <span>many

Answer D. (x>2.5)
We are given two points: (-1, -1) and (1, -4). Slope is calculated as the change in y over the change in x, or rise over run.
The change in y is the difference of the two y coordinates (it doesn't matter the order): -1 - (-4) = 3
The change in x is the difference of the two x coordinates (this order depends on the order that you subtracted the y coordinates; they must be the same order): -1 - 1 = -2.
So, the slope is 3/-2
