Answer: 1/3 =0.33
Step-by-step explanation:
just substitute the values of x and y into the expression to get
4(2)+1 /3(3)^2
=8+1 /3×9
=9/27
=1/3
=0.33
It's 6!
When you multiply both the numerator and denominator by the same number, you will have an equivalent to the fraction you started with because the new fraction can be reduced to the original fraction.
2/3 = 4/6 = 6/9 = 8/12 = 10/15 = 12/15 etc.
I think you can solve it by
=(x^2 - y^2) *( x^2 + y^2)
= (x -y)*(x+y)*(x^2 + y^2)
