How many solutions does a system of equations have when solving results in the statement 3 = 5?

An equation of the line tangent to y=x^3+3x^2+2 at its point of inflection is

Three numbers x, y, and z are in the ratio 2: 7: 8. if 12 is subtracted from y, then three numbers form a geometric sequence (in the order x, y–12, z). find x, y, and z. there are 2 sets.

The measure of angle 0 is 600 degrees
