Answer:
4c² + 11cd + 5d
Step-by-step explanation:
To add monomials, you have to look at the variables that are accompanied by their coefficients. In the given problem, (–4c2 + 7cd + 8d) + (–3d + 8c2 + 4cd), you can combine both cd ut nt cd and c² and cd and d and d and c² because they have different variables.
(–4c2 + 7cd + 8d) + (–3d + 8c2 + 4cd)
(-4c² + 8c²) + (7cd + 4cd) + (8d - 3d)
4c² + 11cd + 5d
0.625 which is approximately equal to 0.63 is 5/8 in decimal form.
The volume would be 201.06
1 gallon = $3 so the ratio would be 1:3 where 1 would represent the gallon and 3 the price
6/9=2/3 because we divide both sides by 3
hope this helps
