Lets set our x's apart first, the 5 can only be multiplied by 1 and 5 to get it so lets put a 5 in one side and a 1 in the other... it should look like (5x )(1x )
now we have a postive in the first term and a negative in the second, this means that there will be a positive and a negative sign... now lets see what can be multiplied by 50 that can add to be 15.. lets try 25 times 2 it gives you 50 but lets check if it gives you 15 in the middle,,lets set it up like this (5x+25)(1x-2) if you multiply these will you get 5x2+15x-50?? yes you will!! so which of these factors are alike to your answer?? well the only one would be (x-2), this means your answer would be letter C
Hope this helps
Answer:
10
Step-by-step explanation:
There are as many palindromic 12-bit binary strings as there are permutations with repetition of 6-bit binary strings, which is equal to

.
There are also only two permutations with repetition of 6-bit binary strings, that when each of them is mirrored and the result is "glued" to the right side of the original string, will give a palindromic string without 10 as a substring.
Those strings are 000000 and 111111.
Therefore there are

palindromic 12-bit binary strings with 10 as substring.
Explanation:
<em>What is an eighth of 32?
</em>
An eighth of 32 means 32 is divided into eight equal parts.
Let's use a fact family for this problem:
8 * ? = 32
32 / 8 = ?
-------------
8 * 4 = 32
32 / 8 = 4
An eighth of 32 is 4.
Five eights of 32:
Five eighths of 32 is five times four which is 20
20 is 5 eighths of 32
5/8 * 32 = 20
32 * 5 / 8 = 20
The answer is 32.
