For a hot air balloon to take off, the temperature of the air outside the balloon must be at least 15°F cooler than the temperature of the air inside of the balloon. In interval form, what is the temperature inside the balloon if it is 70°F outside?

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
