Find the product.

a^4(3a ^2 - 2a + 1)

Answers


                   a⁴(3a² - 2a + 1)

We just have to multiply each term inside the parentheses by  a⁴  .

           a⁴(3a²        )  =  3a⁶
 
           a⁴(    - 2a    )  =  -2a⁵
 
           a⁴(            1)  =  a⁴

Now, just addum up :      3a⁶ - 2a⁵ + a⁴

Answer:

3A^6-2a^5+a^4

Answer: 5 oz

Step-by-step explanation:

you get more and for the price of 7.35 it’s not worth only getting three oz

Next-door neighbors Bob and Jim use hoses from both houses to fill Bob's swimming pool. They know that it takes 12 h using both hoses. They also know that Bob's hose, used alone, takes 20% less time than Jim's hose alone. How much time is required to fill the pool by each hose alone?

Answers

Final answer:

Jim's hose takes 15 hours while Bob's hose takes 12 hours to fill the pool when used individually.

Explanation:

This is a mathematical problem that can be solved using the concept of rates.

Let x be the time taken by Jim's hose to fill the pool alone. Since Bob's hose is 20% faster, it takes 0.8x hours to fill the pool alone. We know that work done is inversely proportional to the time taken, we set up the equation 1/x + 1/0.8x = 1/12 (since together they fill the pool in 12 hours).

On solving this equation, we get x= 15 hours (Jim's hose) and 0.8x = 12 hours (Bob's hose).
