Answer:
35 students.
Step-by-step explanation:
If there are 100 students at the school and 35% of them voted for the bear, it means 35 students voted for the bear (100*0.35=35).
The simplified form of the function will be (√10 - √10 + √15 - √21 ).

What is an expression?</h3>
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division.
The expression will be calculated as:-
(√2 + √3 ) ( √5 - √7 ) = √2 (√5 + √7 ) + √3 ( √5 - √7 )
= √2√5 + √2√7 + √3√5 - √3√7
= √10 + √14 + √15 - √21
Therefore simplified form of the function will be (√10 - √10 + √15 - √21 ).

3x+4y=11
4y=11-3x
Substituting this into x+4y=9
X+11-3x=9
-2x=9-11
-2x=-3
2x=3
X=3/2
Substituting this into x+4y=9
3/2+4y=9
4y=9-3/2
4y=18/2-3/2
4y=15/2
Y=15/2/4
Y=15/8
X=1 1/2
Y=1 7/8
