4 0

Answer:

210

Step-by-step explanation:

Formula I made up: (Don't copy it please) (x-1 + x-2 + x-3... until x-(x-1)

Add all answers possible. (4 true and falses with 2 different answers each.) (3 multiple choice with 4 possible outcomes.)

4 x 2 = 8 | 3 x 4 = 12 |

\ /

8 + 12 = 20

Do what I like to call Additional factorial. (it's a little different, so follow the formula above.)

x = 20

20 -1 + 20 - 2... 20-(20-1) = 210

19 + 18... + 1 = 210

Compare my answer to others if you get any because I am just in 8th grade and I am a nerd at math and I love it. Because I am in 8th grade, I have a slight possibility for being wrong. Enjoy the answer and thanks for letting me use my skills for the world. :)

Find the product.

4vir4ik [10]

Answer :

$6{y}^{4} {z}^{2} + 12 {y}^{3} {z}^{2}-3 {y}^{3} {z}+3 {y}^{2} {z}^{2}$

Step-by-step explanation :

To find the product of

$3 {y}^{2} z(2 {y}^{2} z + 4yz - y + z)$

First we expand the bracket ,

it implies that, we use the expression outside the bracket to multiply individual expressions inside the bracket.

Hence

$3 {y}^{2} z(2 {y}^{2} z + 4yz - y + z)$

$= 3 {y}^{2} z(2 {y}^{2} z) + 3 {y}^{2} z(4yz) - 3 {y}^{2} z(y )+3 {y}^{2} z( z)$

we now apply the law of indices

${a}^{m} \times {a}^{n} = {a}^{m+n}$

meaning, when you are multiplying two expressions with the same bases , repeat one of the bases and add the exponents.

Then, simplify to obtain

$= 6{y}^{4} {z}^{2} + 12 {y}^{3} {z}^{2}-3{y}^{3} {z}+3 {y}^{2} {z}^{2}$
