Answer:

In order from top to bottom, the tiles are,

x=5+4i

x=-4+5i

x=4-5i

Step-by-step explanation:

All of these solutions are complex numbers, which means the equation has imaginary roots. Complex numbers are written in the form of a+bi, where a is a real number and bi represents the imaginary number. For quadratic equations, complex roots are often also complex conjugates. This means that the solution is x=a<u>+</u>bi, so to find the other conjugate simply switch the sign. For example, if x=5-4i is a solution, so is x=5+4i.

Step-by-step explanation:

If the diameter is 12, then the radius must be 6. Following the formula of pi: 2 * pi * radius, our result is 37.7. 37.7 * 10.50 is 395.85

I really hope this helps. My memory of circles and pi isn't the best.
