I got -15 as the answer, hope it works
Let's consider the standard and usually used value of irrational numbers given in the question.
- It is asked to see which is closed to 5.66
So, let's see the options:
A) GiveN:

Let consider π = 3.14



B) GiveN:

Here also, let's consider the value be 3.14



C) GiveN:

Let's consider the value of √2 be 1.414


D) GiveN:

Let's consider the value of √3 be 1.732


So, we can see that we have got the approximate value of all the numericals, and the closest to 5.66 is 5.6516 which is the answer of Option C.
So, Correct answer is C

The shortest side is 9, longest is 17 of the triangle IS NOT a 90 degree triangle
The weight of the new student is 27 kg.
Average weight
= total weight ÷total number of students
<h3>
1) Define variables</h3>
Let the total weight of the 35 students be y kg and the weight of the new student be x kg.
<h3>2) Find the total weight of the 35 students</h3>
<u>
</u>
y= 35(45)
y= 1575 kg
<h3>3) Write an expression for average weight of students after the addition of the new student</h3>
New total number of students
= 35 +1
= 36
Total weight
= total weight of 35 students +weight of new students
= y +x

<h3>4) Substitute the value of y</h3>

<h3>5) Solve for x</h3>
36(44.5)= 1575 +x
1602= x +1575
<em>Subtract 1575 from both sides:</em>
x= 1602 -1575
x= 27
Thus, the weight of the new student is 27 kg.
Answer:
x = 3
Explanation:
15x + 5 + 22x + 4 + 60 = 180
37x + 69 = 180
37x = 111
x = 3
