The length of a rectangle is 5in more than 3 times it's width . the quadratic function f(x)=x(3x+5) represents the area of the rectangle in terms of its width . what is a reasonable domain of the function?

Without multiplying, tell which product is larger and why. 5 × 1/3 or 5 × 2/3 a)5 × 1/3 because 1/3 is less than 2/3 b) 5 × 1/3 because 1/3 is greater than 2/3 c) 5 × 2/3 because 1/3 is less than 23 d) 5 × 23 because 1/3 is greater than 2/3

Find the solution on the interval [0, 2pi)
