20 % of n = 40. To solve for n, we must first come up with the appropriate algebraic expression.

20 % of n = 40
0.2 of n = 40
0.2n = 40
n = 40/0.2
n = 200

The value of n = 200.

How would you write 2x^2-7=11 in both quadratic property and square root property?
dangina [55]

Answer:

Quadratic Property 2x^2-18=0

Square Root Property x=√9 or x=+3 or x=-3

Step-by-step explanation:

Quadratic Property or a quadratic Function is of the form ax^2+bx+c=0. So our task is to equate the given expression to zero. We can equate the expression to zero by subtracting 11 on both the sides. In doing so, we get 2x^2-18=0. This is the quadratic Property of the given Expression.

Square property is finding the value for x. we have make x equal to some value. Since we already have the quadratic Property as 2x^2-18=0, we can use this to find the value of x.

so, 2x^2=18

or x^2=18/2=9

or x=√9= +3 or -3.

Is there a relationship between the area and the perimeter of a rectangle
maksim [4K]
Well, an area and perimeter have formula's. The formula of area is length times width. The formula of perimeter is to basically length plus length plus width plus width. For instance, let's say the rectangles width is 5 and length is 6. So you do 5 plus 5 which is 10 and then 6 plus 6 which is 12. And then, 12 plus 10 equals 22. So the perimeter would be 22. If you were to find the area, you would do 6 times 5 and the area would be 30.
I hope this helps :)

In exercises 1 and 2, Find the value of x.
Kruka [31]

From the given picture, we can see that 2 sides are congruen, then the given triangle is an isosceles triangle. In this triangle the base angles are congruent, so we can draw the following picture:

Now, since interior angles of any triangle add up to 180 degrees, we have

x+\frac{x}{2}+\frac{x}{2}=180

By combining similar terms, we get

\begin{gathered} \frac{4}{2}x=180 \\ 2x=180 \end{gathered}

Then, x is given as

\begin{gathered} x=\frac{180}{2} \\ x=90 \end{gathered}

Therefore, the answer is x=90 degrees
