Answer:
x^2 + x -12
Step-by-step explanation:
I am going to expand and simplify because you haven't mentioned what to do:
(x-3)(x+4)
x^2 +4x -3x- 12
x^2 +x-12
Inbetween each term, you are multiply by 4.
10 x 4 = 40
40 x 4 = 160
160 x 4 = 640
640 x 4 = 2560
Your next numbers are 640 & 2560.
hope this helps

1, 3, 9
Step-by-step explanation:
the nine can be divided by those three numbers and no more
Answer:
Center: (9, 4)
Radius: 20
Explanation:
(x - 9)² + (y - 4)² = 400
The Circle Formula:
(x - h)² + (y - k)² = r²
where (h, k) is center points, r is radius
Rewrite the equation:
(x - 9)² + (y - 4)² = 20²
Identify following:
h = 9, k = 4, radius = 20
