Answer:

4c² + 11cd + 5d

Step-by-step explanation:

(–4c2 + 7cd + 8d) + (–3d + 8c2 + 4cd)

-4c² + 7cd + 8d - 3d + 8c² + 4cd (opening bracket)

8c²-4c²+7cd + 4cd + 8d - 3d

= 4c² + 11cd + 5d

Answer:

4c^2 + 5d + 11cd

Step-by-step explanation:

Hey next time please write the numbers that have exponent like this: (Ex: 3x^2)

(-4c^2 + 7cd + 8d) + (-3d + 8c^2 + 4cd)

Combine like terms

-4c^2 + 8c^2 = 4c^2

Combine Like Terms

7cd + 4cd = 11cd

Combine Like Terms

8d - 3d = 5d

Results:

4c^2 + 5d + 11cd
