Answer:

9d^2/(2d + 4).

Step-by-step explanation:

18d^2 / (4d + 8)

First factorise the denominator:

= 18d^2 / 4(d + 2)

The GCF of 18 and 4 is 2 so this simplifies to:

9d^2/2(d + 2)

= 9d^2/(2d+ 4).

If you’re looking for an equation for both of these, Bob’s rentals would be 20+2m and Bella’s would just be 6m. If you are trying to figure out how many movies it would take to be the same, set up the equation 20+2m=6m and solve. Im not exactly sure what you are asking for but I hope this helps.

I hope this helps

$\cfrac{5+3 \sqrt{5} }{ \sqrt{5} } =\cfrac{(5+3 \sqrt{5}) \sqrt{5} }{ \sqrt{5}* \sqrt{5} }= \cfrac{5 \sqrt{5}+15 }{5} = \cfrac{5 (\sqrt{5}+3) }{5} = \sqrt{5}+3$
