Express 17.28 as a mixed number.

Answers

Answer 1
Answer: 17.28
= 17+ 0.28
= 17+ 28/100
= 17+ (28/4) / (100/4)
= 17+ 7/25
= 17 7/25

The final answer is 17 7/25~
Answer 2
Answer: Since 0.28 extends to the hundredths place, your mixed number starts off as 17 28/100.
Simplify 28/100 to 7/25.
Now, your mixed number is 17 7/25.

Answer:

{x}^(3)  +  {x}^(2)  - 18x - 8

Step-by-step explanation:

The given expression is:

(x - 4)( {x}^(2)  + 5x + 2)

We need to expand using the distributive property:

x( {x}^(2)  + 5x + 2) - 4( {x}^(2)  + 5x + 2)

This implies that:

{x}^(3)  + 5 {x}^(2)  + 2x - 4 {x}^(2)  - 20x - 8

Regroup similar terms and simplify:

{x}^(3)  +  {x}^(2)  - 18x - 8

The first choice is correct.

Answer:  A) x³ + x² - 18x - 8

Step-by-step explanation:

  (x - 4)(x² + 5x + 2)

= x(x² + 5x + 2) - 4(x² + 5x + 2)

=   x³  + 5x² + 2x - 4x² - 20x - 8

=   x³ + (5x² - 4x²) + (2x - 20x) - 8

=  x³  +       x²        +     -18x      - 8

Answers

Distribute -3 to get rid of the parentheses.
Add 15 to both sides.
Now divide -3 on both sides.
You have your answer!

What is 2x2?

Answers

Two times two is four (4), if that is what you need. 
You just add that same number to the base when it comes to multiplication. For example, if you had 4x2, then that would be 4 + 4, which is 8. 

Hi there, 2*2 is 4. Multiplication is repeated addition. I hope this helps, have a good day/evening. :)

Miles is planning to spend 2/3 as many hrs bicycling this week as he did last week. Is Miles going to spend more hrs or fewer hrs bicycling this week than last week? ( I'm working on comparing fraction factors and products- multiplying fractions)

Answers

He would be spending less time because  2/3 is not a full number. Let's make an equation out of the: 2/3(m). Note: 3(2) means 3 times 2 and the m is the amount of miles biked last week. We could insert the number 3 to our equation. 2/3(3). Now if you do it the proper way, it is 2/3(3/1) and if you do the math it is 6/3 aka 2. And 2 is less than 3. So it is less time spent
miles is going to spend less hours this week

A ________ is a whole number that divides another whole number with a remainder of 0

Answers

It's a factor. This concept is widely used throughout algebra, and you'll probably bump into it through the end of high school and beyond.

A common use is expressing a term in prime factorization, or reducing a number to its most base parts- primes. For example:

20 = 4 * 5 = 2 * 2 * 5

Of course, a number like 13 which is already prime is made up of itself and 1. Factors do not have to be primes. 20 is also reducible through combinations of 1, 2, 4, 5, 10, and 20. Prime factorization is just a handy example.

Basically, factors multiply with each other to create other numbers, and numbers can be reduced down to their factors.
