No. The circle can be composed of completely negative coordinates, but the radius is always a positive value. You can prove this by plugging any point and the center into the distance formula.

Anyone know how to expand 5p(p-3)
Katyanochek1 [597]
I believe what your asking is just multiplying it together so 5p(p-3) would be 5p2-15p. the p2 is p squared or a little 2 on top of the p. Hope I helped!

Po is trying to solve the following equation by completing the square: 49x^2+56x-64 = 0. He successfully rewrites the above equa
ohaa [14]

Answer:

The answer is 91

Step-by-step explanation:

We have the following equality:

49x^2+56x-64=a^2x^2+2abx+b^2-c

Then a must satisfy that 49=a^2. So,

a=7 or a=-7.

1) If a=7, then, it follows for the first equality that 56=14b. Then b=4. Finally, substituting b=4 in the first equality we obtain that -64=16-c. So, c= 80. We conclude that

a+b+c=7+4+80=91.

As the problem states, we only consider values of a greater than zero. Then 91 is the only solution for a+b+c.
