HELP! PLZ Let $x^2+bx+c = 0$ be a quadratic whose roots are each two more than the roots of $3x^2-5x-7$. What is $c$?

Explain how you can use the triangle sum theorem to find the measures of the angles in an equilateral triangle. the angles of an equilateral triangle are . let the measure of each angle be x. then, by the triangle sum theorem, x + x + x = 3x = ° solving for x gives x = °

The physical fitness of an athlete is often measured by how much oxygen the athlete takes in (which is recorded in milliliters per kilogram, ml/kg). the mean maximum oxygen uptake for elite athletes has been found to be 60 with a standard deviation of 7.2. assume that the distribution is approximately normal.
