Answer:

533 sq. ft.

Step-by-step explanation:

First find the area of the rectangle on the bottom:

22*13=286

Then in your head move the triangle on the right to the other side to create a triangle (if this doesn't make sense tell me in a comment)

It will turn into a rectangle that is 13 by 19 so find the area of that:

13*19=247

Then add the areas together:

286+247=533

If x − √a is a factor of 2x4 − 2a 2x 2 − 3x + 2a3 − 2a2 + 3 , find the value of a.

iragen [17]

Answer:

$\boxed{\sf \ \ \ a = 1 \ \ \ }$

Step-by-step explanation:

Hello,

saying that $x-\sqrt{a}$ is a factor means that $\sqrt{a}$ is a zero which means

$2(\sqrt{a})^4-2a^2(\sqrt{a})^2-3*\sqrt{a}+2a^3-2a^2+3=0\\\\ 2a^2-2a^3-3*\sqrt{a}+2a^3-2a^2+3=0\\\\3-3*\sqrt{a}=0\\\\\sqrt{a}=\dfrac{3}{3}=1\\\\ a = 1$

so the solution is a = 1

Find the equation of the line parallel to the line y = 2x + 3 and expect oy in (0; 1)

nignag [31]

Step-by-step explanation:

Any lines that are parallel to each other have the same slope (coefficient of x is the same)

In this case, y = 2x + c.

Since it includes the point (0, 1), the y-intercept is 1 and that is c itself.

Hence, the equation of the parallel line is y = 2x + 1.

What is the constant of variation for the following table? If your answer is in the form of a fraction, write your answer in as

nikklg [1K]

Answer:

1/4

Step-by-step explanation:

Change is y (f9x) over the change in x.

Look at the f(x) column.

What is the change from -2 to -1? 1

What is the change from -1 to 0? 1

What is the change from 0 to 1? 1

What is the change from 1 to 2? 1

We see that this change is constant. It is always 1.

Look at the x column.

What is the change from -8 to -4? 4

What is the change from -4 to 0? 4

What is the change from 0 to 4? 4

What is the change from 4 to 8? 4

We see that the change is constant. It is always 1.

When we put this change the form a/b we get 1/4
