This is 4.

Since 1+1+1+1+0=4.

Nice, Chris!!!

x=The number of red marbles

y=The number of blue marbles

Equation 1: x+y=27

Equation 2: x=3y-5

27-y=3y-5

3y+y=27+5

y=8

x=3y-5

x=3*8-5

x= 19

The number of red marbles is 19

The number of blue marbles is 8

Of course. And thanks for your advice!

I agree! Nice job, EP!

Thanks!!!

Squared, so technically two dodecahedrons, I think.

Hint:

Phase Shift: −π/6 (π/6 to the left)

Vertical Shift: 0

THANKS MATHWAY!

Nice, Guest! Another hint would be:

Since a dodecahedron is inscribed in a circle with radius one, \((P_1 P_2)^2 + (P_1 P_3)^2 + \dots + (P_{11} P_{12})^2.\) would be TWO dodecahedrons.

Wow! Nice job!
