You multiply 320 by 3 and the answer is 960

The balloon's total change in altitude is -960.

Because 320 x 3 = 960 and it's descending (negative).

What value(s) of x make the equation x2 - 18x + 81 = 0 true?

We can factorise this to get (x-9)(x-9). To find the value, each bracket needs to equal 0, so the value would be x=9

For what value of x is the rational expression below undefined?

Blizzard [7]

Answer: The expression is undefined for x=4 and x=5.

The expression is undefined for any x that makes the denominator 0. This leads to solving a quadratic equation:

$\frac{x+3}{x^2-9x+20}\\x^2-9x+20\neq 0\\x_{1,2}\neq\frac{9\pm\sqrt{9^2-80}}{2}=\frac{9\pm1}{2}\\x_1\neq4\\x_2\neq5$
