Ok, so I'm pretty sure this one is 11.5 I just wanted to make sure with u guys! :)

Which equation can be rewritten as x + 4 = x2?

Right ans is √x+4 = x

❣️

The equation x + 4 = x²  will be written as √( x+2 ) = x. The correct option is B.

In mathematics, expression is defined as the relationship of numbers, variables, and functions using mathematical signs such as addition, subtraction, multiplication, and division.

The given expression is x + 4 = x². The given expression will be simplified as below,

x + 4 = x²

Remove the square and apply the square root on the left side of the equation.

x = √ ( x + 4 )

Therefore, the equation x + 4 = x²  will be written as √( x+2 ) = x. The correct option is B.

Step-by-step explanation:

Because changing from centimeters to meters does not affect the value of the correlation, the correlation will remain 0.964.

The effect does have on the correlation of the two variables should be that it remain the same i.e. 0.964.

Since there is the changing from centimeters to meters so this does not impact the correlation value due to which it remain the constant i.e. 0.964.

Also, the correlation coefficient should be unit -less and the value should always ranged between -1 to 1.

Therefore, it remains the constant.

Answer:

4n+2=15

Step-by-step explanation:

You have 4 of the value n being added together plus an additional two, the length of which is equal to 15. Repeatedly adding n 4 times is the same as saying multiply n by 4 and then add 2. Therefore, 4n +2 is the best answer.

Answer:

First option, and the expanded form is:

f(x) = x^4 - 7*x^3 + 7*x^2 + 21*x - 30

Step-by-step explanation:

Notice that in the answer we have the general form:

p(x) = x^4 - a*x^3 + b*x^2 + c*x - d

Where a, b, c, and d, are real positive numbers.

Knowing that we have a polynomial of degree 4, we can discard the third and fourth options, because these ones have a degree of 2 and 3.

Now we can look only at the first and second option, let's expand them and see which one is the correct option.

First option:

f(x) = (x - 2)*(x - 5)*(x - √3)*(x + √3)

Remember that:

(x^2 - a^2) = (x - a)*(x + a)

then the last two parts of the f(x) equation can be rewriten as:

(x + √3)*(x - √3) = (x^2 - √3^2) = (x^2 - 3)

Now we can rewrite the f(x) equation as:

f(x) =  (x - 2)*(x - 5)*(x^2 - 3)

Now we can just expand this, we have:

f(x) = (x^2  -5*x - 2*x + 10)*(x^2 - 3)

f(x) = (x^2 - 7*x + 10)*(x^2 - 3)

f(x) = x^4 - 3*x^2 - 7*x^3 + 21*x + 10*x^2 - 30

f(x) = x^4 - 7*x^3 + 7*x^2 + 21*x - 30

We can see that this option already matches the structure we wanted:

f(x) = x^4 - a*x^3 + b*x^2 + c*x - d

(look at the signs)

So we can conclude that the correct option is the first one, and the expanded form is:

f(x) = x^4 - 7*x^3 + 7*x^2 + 21*x - 30

Answer:

640 units squared

Step-by-step explanation:

The shape below is a trapezoid.

The formula for the  area of a trapezoid is average of the bases times the height.

The bases are the parallel lines that make up 2 of the sides of the trapezoid.

The height is the line dotted line that creates right angles and is the distance between the two bases.

The bases are 24 and 40.

To find the average, we add them together and divide by 2

(24+40)/2=64/2=32

Now, we multiply 32 by the height, which is given as the length of 20.

32*20=640

the area of the trapezoid is 640 units squared

Hope this helps!
