Add. Your answer should be an expanded polynomial in standard form. (d^2+6d+9) +(d^3+6d+9)=

d^3 + d^2 + 12d + 18

Step-by-step explanation:

(d^2 + 6d + 9) + (d^3 + 6d + 9) =

First, step is to drop the parentheses since they are not needed.

= d^2 + 6d + 9 + d^3 + 6d + 9

Now, like terms together.

= d^3 + d^2 + 6d + 6d + 9 + 9

Add like terms.

= d^3 + d^2 + 12d + 18

step-by-step explanation:

i believe its "c" because all of the other options include a but it could be d because there is a way of financing with cash at certain places but its uncommon.
