Hi Nova
(4u³+6u²+7)+(6u³-2u+7)
= 4u³+6u²+7+6u³-2u+7
Combine like terms
( 4u³+6u³)+(6u²)+(-2u)+(7+7)
= 10u³+6u² -2u+14
There no like terms so you can not simplify the sum
I hope that's help and if you have questions please ask !

Answer:
1, (-5)(8)=-40 2, (4)(-4)=-16. 3, (-1)(-9)=9. 4 , (5)(6)=30. 5, (12)(-2)=-24. 6, (‐15)(9) =-135. 7. (5)(‐6)= -30. 8. 6(‐6) = -36. 9. (‐27)(14) = - 378. 10.(‐32)(0) = 0. 11.(128)(‐3)= -384. 12.(‐54)(‐4) = 216. 13.(+21) ÷ (+7)= +3
Step-by-step explanation:
positive number multiplied by positive number gives positive number
negative number (-ve) times positive number (+ve) gives -ve
-ve times -ve gives +ve
+ve times -ve gives -ve
hope it helps
