25 kids in all
2xboys:3x girls
so the equation would be
2x+3x=25
solve,
5x=25
/5 /5
x=5
2x=10
3x=15
10 boys and 15 girls
25 and 11... so, ultimately, it would be 36 feet of fencing that he needs.

Here we can simplify the product by multiply the square root 2 with square root 2 first.

=3*2
=6
So answer is 6
the answer to this is x= -1
