Find the reciprocal of the second fraction (flip numerator and denominator's spots) and multiply the two fractions.
Answer:
-x^2+4x+6
Step-by-step explanation:
f(x) = 4x+1
g(x) = x^2 - 5
(f-g) (x) = 4x+1 - ( x^2 - 5)
Distribute the minus sign
= 4x+1 - x^2 +5
Combine like terms
= -x^2+4x+6

Answer:
10℉
Step-by-step explanation:
9,000 feet - 4000 feet (because the camp is 4000 feet above sea level) = 5000 feet
for every 1000 ft you decrease by 3.6℉ therefore 5(3.6) = 18 degrees
when you get to the top it is -8℉ to find out the temp at base camp you just add 18 ℉ to the final tempreture
-8 +18 = 10℉
