First you want to organize it from least to greatest: 4, 5, 5, 6, 10, 11, 12, 13

Then look for the one in the middle. But oh wait there are 2 so you need to add 6 and 10 then divide it by 2 to get a median of 8.

A song I learned back then is this I don't know who it is by though: Mode, mode, mode is the most, Average is the mean.Median, median, median, median, The number in between.

How do i factor x^4+6x^2-7 completly?

liq [111]

The factoring can be done similarly to a quadratic equation thanks to x^4 being the square value of x^2.

x^4 + 6x^2 - 7
x^4 - x^2 + 7x^2 - 7
(x^4 - x^2) + (7x^2 - 7)
x^2(x^2 - 1) + 7(x^2 - 1)
(x^2 + 7)(x^2 - 1)
(x^2 + 7)(x - 1)(x + 1)

Factored completely we get: (x^2 + 7)(x - 1)(x + 1)

Simplify the following rational expression

madreJ [45]

Step-by-step explanation:

as the denominator (x+3) is in both you need only one denominator to be multiplied in first rational number .

2x (x-2). + 5.

(x+3) (x-2). (x+3) (x-2)

2x^2-4x +5

(x+3) (x-2)

it's cannot be solved after that.

(x+y,y+3)=(6,2y) find the value of x and y

trasher [3.6K]

Step-by-step explanation:

Solution:

Given:-

(X+y,y+3)=(6,2y)

Equating corresponding elements,we get,

X+y=6------(1)

y+3=2y-----(2)

solving equation (2),

y-2y=-3

-y=-3

y=3.

Now, substituting y=3 in equation (1)

X+3=6

X=6-3

X=3

Therefore,. (X,Y) = (3,3)

Use the protractor tool to measure the angle.

Aneli [31]

Answer: i belive its 140 i really coudn't tell.

Step-by-step explanation:

I used the protactor and I aligned it agaist the problem. Hope this helps. :)

By that i meant i got my protactor and I aligned it on the tiny dot you can see, the arrow pointed onto the number. I really don't think there is much to explain. If their is any confusion i will re-write it.

This is confusing... can someone help me?! Please

Alex_Xolod [135]

So if you convert the numbers to numerical form it is 20+20+30=70
20+20=40
40+30=70
If you still don't understand feel free to ask for more help
