Answer:
48
Step-by-step explanation:
1 gallon=16 cups. So, 3x16=48 cups.
The answer would be 3n^2 + 2.
This can be found/proven by replacing "n" with term number (1,2,3,4...), then solving to get the final number. For example 3 * 1^2 + 2. You would first do 1^2, which is 1. Next, you would multiply 1 by 3, to get 3. Finally, you'd and the 2 to get 5. 5 is the 1st term, and you can use this same equation to get the rest of the terms you need.
I hope this helps!
Answer:
No
Step-by-step explanation:
4*1 = 4, not 0.
Answer: -1
Step-by-step explanation: To evaluate this problem, the first thing we want to do is plug in the appropriate value for <em>x</em>.
When we do that, we get 
A good rule of thumb for problems that involve division bars is to simplify what's above the division bar as much as you can and what's below the division bar as much as you can before you do your dividing.
So up top if we follow our order of operations, the first thing we want to do is square the -2 before we subtract. So -2² is +4.
So in our numerator we have 4 - 8.
Down below, we have -2 + 6 which is +4.
4 - 8 is -4 and -2 + 6 is +4.
