Simplify (-2+3i)(-2+3i) into ax2+bx+c form

What is the solution to the equation? k/6.4=8.7 2.3 5.568 15.1 55.68

Why is studying fractions important

The temperature of a chemical solution is originally 21 ? c . a chemist heats the solution at a constant rate, and the temperature of the solution 75 ? c after 1212 12 minutes of heating. the temperature, tt t , of the solution in ? c is a function of x , the heating time in minutes. write the function's formula.
