As long as your indexes are the same (which they are; they are all square roots) and you radicands are the same (which they are; they are all 11), then you can add or subtract.  The rules for adding and subtracting radicals are more picky than multiplying or dividing.  Just like adding fractions or combining like terms.  Since all the square roots are the same we only have to worry about the numbers outside.  In fact, it may help to factor out the sqrt 11: (5-12-2) \sqrt{11}.  The numbers subtract to give you -9.  Therefore, the simplification is -9 \sqrt{11}

Plz help I will give you BRAINLIESt 5stars
Svetradugi [14.3K]

Answer:

I will just give you the way of solving it

Step-by-step explanation:

First you have to change the sgape of the equation and it will become like this :

-6y=-2x+12

And then:

Y=0.33x+2

And then you have to give values to x and find y

For example i will make x zero (0)

It will become

Y=0.33(0)+12

=+12

And the points are (0,+12)

Go on like this and draw the line

Good luck

In 2006,the General Social Survey (which is conducted uses a method similar to simple random sampling) included a question that
mars1129 [50]

Answer:

Assumptions are not met. Can not make confidence interval.

Step-by-step explanation:

In the General Social Survey, sample size is 1514.

The proportion of those who see themselves social is \frac{470}{1514} ≈ 0.31

To give an 95% confidence interval, we should be able to calculate margin of error of the sample mean, which is given by the formula

M±z*\frac{s}{\sqrt{N} }  where M is the mean of the sample (in the General Social Survey it is 0.31), z is z-score for the 95% confidence level(approx. 1.94), s is the standard deviation of the sample, N is the size of the sample(in this example it is 1514).

Since we don't know the standard deviation of the sample, we cannot give a confidence interval.

Find the sum of 7a^3 + 14a +12 and -6a^3 +12a^2 -7
SOVA2 [1]
To find the sum:

{7a}^{3} + 14a + 12  + ( {- 6a }^{3} ) + {12a }^{2}   - 7 \\  = {7a }^{3}   -  {6a}^{3}  + {12a }^{2}  + 14a + 12 - 7 \\  =  {a}^{3}  + {12a }^{2}  + 14a + 5
Therefore the answer is a^3+12a^2+14a+5.
Hope it helps!
