your equation is:
a² + b² = c²
So, plug in what you know.
5² + 12² = c²
5² means 5*5, so your "a" is equal to 25
12² means 12*12, so your "b" is equal to 144
25 + 144 = c²
to this part, add a and b. you'll get 169.
169 = c²
next, use your calculator and square both sides.
√169 = √c²(you don't really have to do anything with the c, just get rid of the ²)
squaring both sides will get rid of the ² in c, and will give you your new number:
c = 13
<span>(x-h)^2 + (y-k)^2 = r^2
(h, k) = (-5, -1)
r = 5
</span><span>(x+5)^2 + (y+1)^2 = 5^2
</span><span>(x+5)^2 + (y+1)^2 = 25</span>
I believe the answer you are looking for is -9<span />
The numbers that fit the description of... my one's digit is two less than my ten's digit ... between 60 and 100 are..
64,75,86,97
97 is the only prime number of those 4.
Hope this helped
