Answer:
x=8 or -8
Step-by-step explanation:
64 squared = 8 or -8
8x8=64
-8x-8 = 64
9514 1404 393
Answer:
56, 60, 64
Step-by-step explanation:
The middle of the three numbers is their average: 180/3 = 60. The other two will be 4 more or less than this.
The numbers of interest are 56, 60, 64.

<em>Additional comment</em>
For "consecutive integer" problems, it is often useful to work with the average of the numbers. The average will be the middle number of an odd number of numbers (as here), or will be halfway between the two middle numbers if their number is even.
Even if you bother to write equations, it can work to do that in terms of the average value (middle number): (x -4) +(x) +(x +4) = 180 in this case.
The square root of 141 =
This is because the two factors are 3 and 47, which both aren't perfect squares. You cannot take anything out.
If you want it simplified (like with a calculator) it would be:
I think the answer is substitution property of equality because you are substituting 9 for y as y=9.
Answer:
n + 3
Step-by-step explanation:
6 is 3 + 3, 11 is 8 + 3 and 12 is 9 + 3 so the output seems to be the input plus 3. Therefore, when the input is n, the output is n + 3.
