The figure is not marked in any way that would indicate it is a parallelogram. If we assume it is, then

... BE = DE

... 10x -3 = 8x -1 . . substitute the given expressions

... 2x = 2 . . . . . . . . add 3-8x

... x = 1 . . . . . . . . . . divide by 2

The appropriate choice is ...

... A. 1 unit

_____

Since the figure is not marked to indicate BE=DE, you could argue that any answer is correct.

Correct answer gets brainliest :) Please help with my homework:)

Answer:

A) 30 cm

B) 20 cm

Explanation:

For the perimeter of rectangle B, I just imagined there was a cut horizontally through the middle. The length would be 5, since its half, and the width would be the same (10) because folding it into a rectangle only changes its length.

I added it up : 5+5+10+10= 30 cm

Rectangle B is 30 cm

For the perimeter of square C, you folded it again to make the width decrease by 5cm , so all the sides were 5cm.

5+5+5+5=20 cm

Square C is 20 cm

Find the measure of X, Y and Z in simplest form:

Inga [223]

Answer/Explanation:

$12^2 = 16*x$ (altitude to hypotenuse theorem)

Solve for x using this equation

$144 = 16x$

$\frac{144}{16} = x$ (division property of equality)

$9 = x$

$x = 9$

$y^2 = 12^2 + x^2$ (pythagorean theorem)

$y^2 = 12^2 + 9^2$ (substitution)

$y^2 = 144 + 81$

$y^2 = 225$

$\sqrt{y^2} = \sqrt{225}$

$y = 15$

$z^2 = (x + 16)^2 - y^2$ (pythagorean theorem)

$z^2 = (9 + 16)^2 + 15^2$ (substitution)

$z^2 = 25^2 + 15^2$

$z^2 = 625 + 225$

$z^2 = 850$

$\sqrt{z^2} = \sqrt{850}$

$z = \sqrt{25*34}$

$z = 5\sqrt{34}$

Explain how possibilism allows people to survive in a tropical environment, PLEASE HELP THIS IS URGENT!!!!!!!

Ostrovityanka [42]

Answer with Explanation:

"Possibilism" is considered a theory in cultural geography. It states that there is a relationship between the natural environment and the people within the communities with which they support. This means that people survive in the environment through different possibilities, but which the environment has set limitations.

In order to survive in a tropical environment, man will be building houses to shade themselves from the scorching heat of the sun. They will also be using "irrigation" in order to supply water essential for the production of crops. These are just some of the possibilities that the man has authority over. However, doing these advancements have limitations, which means man have to choose the best option in order to survive.
