To answer this question, you must first understand what a fourth is. 1/4 is simply when a one is split into four parts, and you take one of those parts. Imagine you have a pie, and you cut it into four equal pieces. If you take one of those four pieces, you have one fourth of the pie. So if you have three fourths of the pie, you have three pieces out of the four total. This question is basically asking: "If you have three pieces out of four, how many pieces do you need to make one whole pie?"
Therefore, the problem looks like this:
3/4 + ?/4 = 1
and therefore the answer is 1/4 because you only need one fourth to make a whole number.

Answer:
n²+1
2n²
Step-by-step explanation:
We can see that 2, 5, 10, and 17 becomes 1, 4, 9, and 16 when we subtract 1.
So it adds 1. The nth will be n² + 1.
2, 8, 18, and 32 is the double of n². 1, 4, 9, and 16 are their half.
So the nth term becomes 2n².
Divide botoh sides by 7
x-12=-3
add 12 to both sides
x+12-12=12-3
x+0=9
x=9
2.25 x 10^-17. Because it's negative you move the decimal to the left. So 2.5 x 10^-8 is .000000025 and 9 x 10^-10 is .0000000009.
