Answer: 2a -5 + h
<u>Step-by-step explanation:</u>
f(x) = x² - 5x
f(a + h) = (a + h)² - 5(a + h)
= a² + 2ah + h² - 5a - 5h
f(a) = a² - 5a
f(a + h) - f(a) = a² + 2ah + h² - 5a - 5h - (a² - 5a)
= a² + 2ah + h² - 5a - 5h - a² + 5a
= 2ah - 5h + h²
= 2a - 5 + h

C. 17
Step-by-step explanation:
The right question is that the lowest altitute is 3^8 feet
You are told that the highest altitude is 3 times the lowest altitude =>
highest altitude = 3 * lowest altitude = 3 * 3^8 feet.
Now you use the ruel of mutiplication of powers with the same base: copy the base and sum the exponents => 3 * 3^8 = 3 ^(1+8) = 3^9.
Note: remember that 3 = 3^1.
