B. -8
F(x) = -3x2 - 2x - 1
0 = -3x x 2 - 2x - 1
X= -8
Answer:
126
Step-by-step explanation:
Row 1: 30+0*4
Row 2: 30+1*4
Row 3: 30+2*4
...
The list goes on. Do you see a pattern here? If we call the row number as r, the formula is 30+(r-1)*4. In the 25th row, the r is 25. So in the formula, it is 30+(25-1)*4=30+24*4=126.

Distance equals end minus start
(-7,-7)-(5,9)=
(-7-5,-7-9)=(-12,-16)
(-12,-16) gives us the distance point coordinates. Now to find the magnitude we can take sqrt((-12)^2+(-16)^2)=20
So the distance between the two points is 20
