35: 83 is the ratio of kids
We call:

as the set of <span>the first 51 consecutive odd positive integers, so:
</span>

Where:





<span>and so on.
In mathematics, a sequence of numbers, such that the difference between two consecutive terms is constant, is called Arithmetic Progression, so:
3-1 = 2
5-3 = 2
7-5 = 2
9-7 = 2 and so on.
Then, the common difference is 2, thus:
</span>

<span>
Then:
</span>

<span>
So, we need to find the sum of the members of the finite series, which is called arithmetic series:
There is a formula for arithmetic series, namely:
</span>

<span>
Therefore, we need to find:
</span>
Given that

, then:

Thus:

Lastly:
Answer:
ASA postulate of congruency
Step-by-step explanation:
Here Given AE=ED and ∠BAE=∠CDE
Also if we clearly observe ∠AEB=∠CED
By ASA postulate those two triangles are congruent.
The ASA (Angle,Side,Angle) postulate states that if two triangles with two angles and the included angle are equal then the two triangles are congruent.
Answer:
xy = 3
Step-by-step explanation:
The expression to be evaluated is:


By some algebraic handling:

Where:

There is one possible solution:
x = 3, y = 1
And consequently,
xy = 3
