Answer:
- Cameron is 13 and Avery is 8 years old
Step-by-step explanation:
Let Cameron's age be x and Avery's age be y.
<u>The difference is 5 and the product is 104:</u>
<u>Solve by substitution:</u>
- xy = 104
- y(y + 5) = 104
- y² + 5y - 104 = 0
- y = (- 5 ± √(5² + 4*104))/2 = (- 5 ± √441)/2 = ( - 5 ± 21)/2
<u>Taking the positive root as age can't be negative:</u>
<u>Find x:</u>
Other method:
zeros of numerator and denominator are x = -2 and x = 4.
Look at the second picture.
for x < -2 → x + 2 < 0 and x - 4 < 0
therefore 
for -2 < x < 4 → x + 2 > 0 and x - 4 < 0
therefore 
for x > 4 → x + 2 > 0 and x - 4 > 0
therefore 
<h3>Answer: B) -2 < x < 4</h3>
