$9.75 for 5 mangos. $19.50 for 13 mangos.

Which expression is equivalent to? assume x > 0 and y > 0.

The lengths of two sides of a right triangle are given. find the length of the third side. round to the nearest tenth if necessary. a) y = 12/5x + 39/5 b) y = 5/12x + 5/39 c) y = 12/5x - 39/5 d) y = 5/12x - 5/39

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