Answer: the first fish was 3/20 feet longer.
Explanation: in order to compare the fractions you need to multiply 12/5 by 4 and 9/4 by 5. That leaves us with 48/20 and 45/20 after that you simply subtract and are left with 3/20.
<span>The perimeter of a Triangle is the sum of three sides ; ie assuming k,l,m be the three sides of a triangle means then k+l+m = perimeter of a triangle.
here given that a two sides lengths are 2x+ 2 and 5x-4 ;
and the perimeter length is 16x-6;
let the unknown side be k;
therefore k + 2x+2 + 5x-4 = 16x-6;
resolving k + 7x-2 = 16x-6;
Ans:-
k= 16x-6-7x+2 = 9x-4 ie the
unknown length k is 9x-4</span>
