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 $a+b+c$ .

polet [3.4K]

Answer:

155°

Step-by-step explanation:

We know that the sum of the sections must be 360°. So, by removing a section of 75° he leaves the paper circle with a section of 185°, then removes another 130° section, leaving the last section of 155°.
