Well start by adding all the numbers together, then divide by how many numbers, which is 15
Answer: It a permutation
Step-by-step explanation: Hope this help :D
Step-by-step explanation:
since the coefficient is the same for the fist three they have the same equation.
the reason: there can only be one line that goes through one point with a specific coefficient.
C = to squares diagonal length
Pythagoras theorem: a^2 + b^2 = c^2
5^2+5^2=c^2
25+25=c^2
50=c^2
square root so c would be about 7.071
Since the diagonal is less than the diameter of the circle, the square will fit inside without touching the edge
