16. 5x^3 y^-5 • 4xy^3
20x^4y^-2

20x^4 • 1/y^2

=20x^4/y^2

17. -2b^3c • 4b^2c^2
= -8b^5c^3

18. a^3n^7 / an^4 (a^3 minus a = a^2 same as n^7 minus n^4 = n^3)
=a^2n^3

19. -yz^5 / y^2z^3

= -z^2/y

20. -7x^5y^5z^4 / 21x^7y^5z^2 (divide -7 to 21 and minus xyz)

= -z / 3x^2

21. 9a^7b^5x^5 / 18a^5b^9c^3

=a^2c^2 / 2b^4

22. (n^5)^4

n ^5 x 4
=n^20

23. (z^3)^6
z ^3 x 6
=z^18

Can someone please help me I will mark u brilliant asp. It’s just true or false questions
Mekhanik [1.2K]

Answer:

False

False

True

True

True

Step-by-step explanation:

There cannot be an orange bead in the bag. FALSE

they never said how many colors are in the bag so there is always a possibility.

There must be exactly 1 yellow bean in the bag. FALSE

Just because Ryan only selected 1 yellow bean doesn't mean there is only 1 in the bag.

After 15 trials, Ryan has selected exactly 6 white beads. TRUE

2/5 = 6/15. Ryan has selected 6 white beads

After 16 trials, the experimental probability of selecting a blue bead is 1/4. TRUE

Ryan has selected 4/16 blue beads at the 16th trial.

After 17 trials, the experimental probability of selecting a red bead is 5/17. TRUE

at trial 17, the red bean ratio is 5/17.

1/3 = 5/15 and then 2 more trials make it 5/17.

How to use the Pythagorean theorem to provee if a triangle with the side lengths 7,14,28 is a right triangle. Plz help
Lapatulllka [165]

Answer: find the answer in the explanation.

Step-by-step explanation:

To use the Pythagorean theorem to prove if a triangle with the side lengths 7,14,28 is a right triangle, you will square 7 and add it to the square of 14. The square root of the sum will be equal to 28 if it is a right angle triangle. Otherwise, it is not.

(7^2 + 14^2) = 49 + 196

245

Find the square root of 245

Square root = 15.65

Since it is not 24, the triangle is not a right angle triangle.
