1/3 (9 - 6x) = x Solve the following please

Dmitriy789 [7]

Hello there!

1/3 (9 - 6x) = x

Start by using the distributive form

(1/3)(9) + (1/3)(-6x) = x

9/3 + (-6x)/3 = x

3 - 2x = x

-2x + 3 = x

-2x - x + 3 = 0

-3x + 3 = 0

-3x = 0 - 3

-3x = -3

x = -3/-3

x= 1

There are 20 marbles in a bag. Each marble has a different design or color. How many ways can you draw 8 marbles from the jar? I

Digiron [165]

Answer:

The number of ways of selecting a combination of 8 marbles from a bag containing 20 marbles is 125970

Step-by-step explanation:

The number of selecting 8 marbles from a bag of 20 marbles

A combination gives the number of possible order or arrangement in a collection of k items selected from a set of n items

$C_{n,k} = \dbinom{n}{k}= \dfrac{n!}{k!\cdot \left ( n - k \right )!}$

In the question, k = 8, and n = 20

Substituting the values of n and k in the above equation gives;

$C_{20,8} = \dbinom{20}{8}= \dfrac{20!}{8!\times\left ( 20 - 8 \right )!} = 125,970$

Therefore, the number of ways of selecting 8 marbles from a bag containing 20 marbles is given by the combination C₂₀, ₈ = 125970.

Expand.<br> Your answer should be a polynomial in standard form.<br> (3c + 2)(c^2-6c-4)

evablogger [386]

Answer:

After expanding the polynomial $(3c + 2)(c^2-6c-4)$ we get $3c^3-16c^2-24c-8$

Step-by-step explanation:

We need to expand the polynomial $(3c + 2)(c^2-6c-4)$

Multiply the terms:

$(3c + 2)(c^2-6c-4)\\=3c(c^2-6c-4)+2(c^2-6c-4)\\=3c^3-18c^2-12c+2c^2-12c-8\\=3c^3-18c^2+2c^2-12c-12c-8\\=3c^3-16c^2-24c-8$

So, after expanding the polynomial $(3c + 2)(c^2-6c-4)$ we get $3c^3-16c^2-24c-8$

HELP HELP PLEASE!! D:<br><br> Determine the missing side length:<br> Please don't give cap!

viktelen [127]

Answer:

c = 35

Step-by-step explanation:

$c^{2} = a^{2} + b^{2}$

$c^{2} = 21^{2} + 28^{2}$

$c^{2} = 1225$

$\sqrt{c^{2} } = \sqrt{1225}$

$c = 35$
