Isolating s, the equation written in terms of s is:

-------------------------
- The equation for the length of the third side, as stated in the problem,("Maristella uses the equation b = 24 – 2s to find b, the length of the triangle's third side") is:

- To solve for the lengths of the congruent sides, we isolate s, thus:


Inverse of multiplication is division, thus:

Separating into two fractions:

Solving each fraction:

The general term of an arithmetic sequence is,

Where ,
= nth term.
= First term
and d = common difference.
The given sequence is: 57, 66, 75, 84, 93, ...
Here
= 57,
d = 66 - 57 = 9
We need to find the 250th term. So, n = 250.
Next step is to plug in these values in the above formula. Therefore,

= 57 + 249 * 9
= 57 + 2241
= 2298
Therefore, 250th of this sequence is 2298
Hope this helps you!
<em>Answer:</em>
The Answer is 300
<h3><em>
Step-by-step explanation:</em></h3>
The answer is 300 because if you look at the hundreds place it is 200 and as my teacher told me, if the number to the right is 5 or greater bump the number up! Since the number is eight the eight will move the two up one digit causing it to be 3 and since that number was moved up all the other numbers become zeros.
So, your answer is 300 or 300.00
