3. Consider equations of the form x-a=√bx+c , where a, b, and c are all positive integers and b > 1. (a) Create an equation of this form that has 7 as a solution and an extraneous solution. Give the extraneous solution.

(b) What must be true about the value of bx+c to ensure that there is a real number solution to the equation? Explain.

The blue whale is the largest animal living on the earth. the average blue whale measures 100 feet long (30 meters) and weighs 300,000 pounds (136,000 kilograms). a whale’s head is 1⁄3 of the length of its body. a new baby whale is 1⁄4 the length of a grown whale. the average man is 1⁄17 the length of a blue whale, and 1⁄1,818 its weight. a human baby measures 1⁄4 of the length of an adult. calculate the following information: how long is a whale’s head? how long is a new baby whale? how tall is the average man? how much does the average man weigh? how tall is the average human baby?
