factor completely 4x5 − 20x4 − 36x3. 4(x5 − 5x4 − 9x3) x3(4x2 − 20x − 36) x2 − 5x − 9 4x3(x2 − 5x − 9)

Answers

Answer 1
Answer:

Consider the polynomial 4x^5 - 20x^4 - 36x^3. It has three terms and their greatest common factor is 4x^3.

Since

4x^5=4x^3\cdot x^2,\n20x^4=4x^3\cdot 5x,\n36x^3=4x^3\cdot 9,

then

4x^5 - 20x^4 - 36x^3=4x^3(x^2-5x-9) (you write in brackets the same sign as the corresponding term has).

Answer: correct choice is D.
Answer 2
Answer:

Answer: 4x^3( x^2 - 5x - 9)

Proof of validity is shown below.

Choose a method the find the product 16x60

Answers

the product is 960 because 0x6=0,6×6=36 so 60 times 6 is 360 thenn you go to the bottom & bring down one zero under your first zero ,multiply 1 times the zero which equals 0 ofc & 6×1=6 so it'll be 360 + 600= 960
The answer is 960 because 16 times 60 is =960

Mrs. Yamaguchi's class weighed the potatoes that they grew in their garden and recorded the data in a table. What are the least and greatest weights of the potatoes in the data set?

Answers

The least and greatest weights of the potatoes in the data set are 1/8 and 3/4 respectively.

How to find the least and greatest weight?

The weight of the potatoes are:

  • 1/4 = 0.25

  • 3/8 = 0.375

  • 5/8 = 0.625

  • 1/2 = 0.5

  • 3/4 = 0.75

  • 1/8 = 0.125

Therefore, the least weight of the potatoes is 1/8 equivalent to 0.125

The greatest weight of the potatoes is 3/4 equivalent to 0.75

A colored chip is yellow on one side and red on the other. The chip was flipped 50 times and landed red side facing up 20 times. What is the relative frequency of the chip landing with the red side facing up?20%
30%
40%
60%

Answers

Number of times red side faced up = 20

Total number of times thrown = 50

Frequency of red side = No of red side / Total    * 100%

                                      =  (20 / 50) * 100%

                                     = 0.4 * 100%

                                     = 40%

Hope this explains it.
20/50 is equal to 40/100 so the answer is 40%
