What is 1,000,000,000 x 1,000,000,000

One positive number is 9 more than twice another. if their product is 95, find the numbers

Which shows the correct substitution of the values a, b and c from the equation 1=-2x+3x^2+1

List the sides of δrst in ascending order (shortest to longest) if: m∠r =x+28°, m∠s = 2x+16°, and m∠t = x+12
