The triangle below is equilateral. Find the length of side x in simplest radical form with a rational denominator.

2x - 20 = 32 20 - 3x = 8 6x - 8 = 16 -13 - 3x = -10

Use the formulas a = x 2 – y 2, b = 2xy, c = x 2 + y 2 to answer this question. one leg of a right triangle has length 11 and all sides are whole numbers. find the lengths of the other two sides. the other leg = a0 and the hypotenuse = a1

Events a and b are independent. the probability of a occurring is 2/5. the probability of b occurring is 1/4. what is p(a and b)?
