Answer:
x = 71/5  (as an improper fraction)
x = 14 1/5 (as a proper fraction
x = 14.2 (as a decimal)
Step-by-step explanation:
It's a rectangle so the diagonals are equal
7x - 9 = 2x + 62
Subtract 2x from both sides
5x - 9 = 62
Add 9 to both sides
5x = 71
Divide both sides by 5
x = 71/5  (as an improper fraction)
x = 14 1/5 (as a proper fraction
x = 14.2 (as a decimal)

The answer is 9 because if there are 3 per kennel, you would do number of kennels*3=number of dogs
number of kennels*3=27
number of kennels=9
