How do i find the vertical asymptote?

  find the value of x that makes the denominator zero: x = 7

Step-by-step explanation:

A vertical asymptote shows up where the denominator is zero. As the denominator gets closer to zero, the function value gets larger without bound (unless there is a numerator factor that cancels the one in the denominator).

To find the value of x at the vertical asymptote, solve the equation ...

  denominator = 0

  x - 7 = 0

  x = 7 . . . . . . . add 7 to both sides

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.
