Remember this rhyme:
Hey Diddle Diddle, the medians the middle:
(Answer for your question: Median is 80%)
You add and divide for the Mean: 
( Answer for your question: Mean is 93)
The mode is the one that appears the most:
( Answer for your question: Mode is 87%)
And the range is the difference between.:
( Answer for your question: Range is 54.)
I hope this helps! :)
        
                    
             
        
        
        

- Simplify :- 1 + - w² + 9w.


Quadratic polynomial can be factored using the transformation  , where
, where  are the solutions of the quadratic equation
 are the solutions of the quadratic equation  .
.

All equations of the form  can be solved using the quadratic formula:
 can be solved using the quadratic formula:  . The quadratic formula gives two solutions, one when ± is addition and one when it is subtraction.
. The quadratic formula gives two solutions, one when ± is addition and one when it is subtraction.

Square 9.

Multiply -4 times -1.

Add 81 to 4.

Multiply 2 times -1.

Now solve the equation  when ± is plus. Add -9 to
 when ± is plus. Add -9 to  .
.

Divide -9+  by -2.
 by -2.

Now solve the equation  when ± is minus. Subtract
 when ± is minus. Subtract  from -9.
 from -9.

Divide  by -2.
 by -2.

Factor the original expression using  . Substitute

<h3>NOTE :-</h3>
Well, in the picture you inserted it says that it's 8th grade mathematics. So, I'm not sure if you have learned simplification with the help of biquadratic formula. So, if you want the answer simplified only according to like terms then your answer will be ⇨

This cannot be further simplified as there are no more like terms (you can use the biquadratic formula if you've learned it.)

Hi there!
We know that the formula for the area of a rectangle is height * width. Thus, we can multiply these two expressions together:

Now, we know through the distributive property that we can distribute the  to everything in the parenthesis. Once this is done, we get:
 to everything in the parenthesis. Once this is done, we get:

Now, we know through the power rule that when two exponents are multiplied together with the same base, the exponent can be added together  . This then would make our equation:
. This then would make our equation:

Giving us for our final answer:

Hope this helps!
