So first add all of the marbles together: 3+2+6+9=20
Because there are 20 marbles together, that would be your denominator. 
All of the other numbers would be your numerator. So you would have:

3/20 green marbles
2/20 yellow marbles
6/20 blue marbles
9/20 red marbles

So your answer would be the probability of picking a red marble from the bag is 9/20 or 45%

Trying to factor by splitting the middle term   

Factoring <span> b2-4b+4</span> 
The first term is, <span> <span>b2</span> </span> its coefficient is <span> 1 </span>.
The middle term is, <span> -4b </span> its coefficient is <span> -4 </span>.
The last term, "the constant", is <span> +4 </span>

Step-1 : Multiply the coefficient of the first term by the constant <span>  1 • 4 = 4</span> 

Step-2 : Find two factors of  4  whose sum equals the coefficient of the middle term, which is  <span> -4 </span>.
<span><span>     </span></span>

<span><span>-4   +   -1   =   -5</span><span>     -2   +   -2   =   -4   That's it</span></span>


Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -2  and  -2 
                     <span>b2 - 2b</span> - 2b - 4

Step-4 : Add up the first 2 terms, pulling out like factors :
                    b • (b-2)
              Add up the last 2 terms, pulling out common factors :
                    2 • (b-2)
Step-5 : Add up the four terms of step 4 :
                    (b-2)  •  (b-2)
             Which is the desired factorization

Select the postulate that is illustrated for the real numbers 5+(-5)=0
ozzi

In this question , we have to find the postulate that is illustrated for the real numbers

5+(-5) = 0

The postulate is Additive inverse postulate which states that

a+ (-a) =0

Where a is the real number and -a is the opposite of a. It states that , if opposite of a number is added with the number, the result is 0 .

Simplify the expression (-3x)^4
Sati [7]
(-3x)⁴

Basically, just do this :

(-3x) × (-3x) × (-3x) × (-3x)

So now you have 9x² × 9x²

9 × 9 = 81

x² × x² = x⁴

So, your answer is 81x⁴

~Hope I helped!~

Determine the number of zeros of the polynomial function <br> F(x) = x^4 - x^7
Tresset [83]

Answer:

7

Step-by-step explanation:

Using fundamental theorem of algebra, there should be 7 roots, if you count multiplicity.

If you're only counting distinct roots, then there should be 4 roots.
