Answer:
a^2-b^2=(a+b)(a-b) where a=4x and b=5. (4x+5)(4x-5)
Step-by-step explanation:
Since both terms are perfect squares,factor using the difference of squares formula
-6.2 plus -4.8 is -11. add the 3.8 to get -7.2
-4.8 plus 3.8 is -1
-1 plus -6.2 is -7.2
-7.2=-7.2
the answer is 200%x=1000 which is =500 when you divide 1000 by 2. So 500 rabbits last year
