Answer:
5 inches
Step-by-step explanation:
(5 + x)(10 + x) = 6x²
x² + 15x + 50 = 6x²
5x² - 15x + 50 = 0
x² - 3x + 10 = 0
(x - 5)(x + 3) = 0
x = 5, x = -3
We want x to be positive, so x = 5.
Thus, each dimension must be increased by 5 inches.

15,000 - 2,500
=12,500 + 3,000
=15,500 - 1,000
=14,500 + 2,500
=17,000 - 3,000
=14,000 ft after 2 hours
