Answer:
63.5 feet/minute
Step-by-step explanation:
She first descended 1,024 feet in 17 minutes
Then she descended 500 feet in 7 minutes
The total feet descended is 1,024 + 500 = 1,524 feet
The total time to descend is 17 + 7 = 24 minutes
The average rate of change in altitude is
Altitude descended / time
1,524 feet / 24 minutes
63.5 feet /minute

Answer:
Her first error was adding the wrong number to both sides. Instead of 4², it should be 2²
Step-by-step explanation:
When completing the square, the number that needs to be added to both sides is (b/2)²
In this problem, b is 4. So, Carly should have added 2² to both sides, but she added 4² instead.
So, her first error was adding 4² to both sides instead of 2²
