Answer:
f(g(x)) = (x+3)^2
Step-by-step explanation
Take the function f(x) and replace the x in this function with g(x)
f(x) = x^2 and replace with x=x+3
f(g(x)) = (x+3)^2
Let c represent the total time during which commercials appeared.
Then 3c+7 = program time = 30 minutes total
Then 3c = 23 minutes, and c = 7 2/3 minutes. This is close to 7.7.

B
Answer:
20,000
Step-by-step explanation:
So, the 2 is the ten thousand and the 3 is in the thousands. 4 or less means to round down so 2<u>3</u>,556 rounds down to a 0 and change the rest to a 0. 20,000. If the number 23,556 had a 5 or more in the thousands, it would have rounded to 30,000 to the nearest ten thousands but it didn't so the answer is 20,000.
