I need help ! Please help me

Answer 1

You can do this !

Since d=3, take your pencil and write the fraction again,
except wherever 'd' appears, write a '3' there instead.

Then you'll have a fraction with nothing but numbers in it, and
you can easily simplify and find the value of the fraction.

I did it in my head as I was looking over the picture, and
I found that the value of the fraction is between 5 and 10.
I don't want to just hand you the answer, because I know
that you can do it.

Answer 2

4d² / (d+1)  when d=3;
therefore:

4(3)² / (3+1)=4(9) / 4=9

Answer:4d² / (d+1)  when d=3 is equal to 9.
