Hi there!
Let's solve this problem step by step!

To find f(3) we must substitute x = 3 into the formula.

Now we use PEMDAS (Parenthesis, exponents, multiply, divide, add, subtract) to find our answer.
Work out the exponents inside the parenthesis first.

And finally multiply.

Hence, the answer is D. 64.

Answer:
w = 1/8t
Step-by-step explanation:
So this is basically saying that for every 1 second that passed, 8 oz of water drip steadily into the bucket which can be expressed like this:
8w = t
Since t represents x and w represents y, we can simplify the equation by moving the 8 to the other side
w = 1/8t
Answer:
10
Step-by-step explanation:
first you need to find the prime factors of the three numbers
ex:
prime factor of 18= 
prime of 24=
there is one 2 and one 3 in common
greatest common multiple 2*3=6
so the greatest common multiple is ten because it is the only one that can divide between all three evenly.

so 10 is your answer
Hello.
17. ( 3 + 5 ) · 8 = 64
18. 4 · ( 6 - 2 ) + 7 = 23
19. 10 ÷ ( 3 + 2 ) · 4 = 8
20. ( 3 + 6 ) · 2 = 18
