Answer:
15u^3 + 8u^2 - 6u + 13
Step-by-step explanation:
(7u^3 + 8u^2 + 8) + (8u^3 - 6u + 5)
= 7u^3 + 8u^2 + 8 + 8u^3 - 6u + 5
= 7u^3 + 8u^3 + 8u^2 - 6u + 5 + 8
*Now add the like terms
= 15u^3 + 8u^2 - 6u + 13
And that is all your can do!
The correct answer is 70 because 420 divided by 6 is 70.
Answer:
- length: 30 ft
- width: 10 ft
Step-by-step explanation:

The length and width of the garden are 30 ft and 10 ft, respectively.
