Parallelogram RECT is a rectangle. If EC = x + y , RT = 2x - y, RE = 2x + y, and TC = 3x - 3 , what are the values of the variab

Lady_Fox [76]

<h2>The values of the variable are 3 and 6.</h2>

Step-by-step explanation:

In parallelogram RECT is a rectangle,

EC = x + y , RT = 2x - y, RE = 2x + y and TC = 3x - 3

To find, the values of the variable = ?

∵ The opposite sides are equal.

∴ RE = TC and RT = EC

2x + y = 3x - 3

⇒ x - y = 3 .......... (1)

Also,

2x - y = x + y

⇒ x - 2y = 0 .......... (2)

Subtracting (1) from (2), we get

∴ x - y - (x - 2y ) = 3 - 0

⇒ x - y - x + 2y = 3

⇒ y = 3

Put y = 3 in equation (1), we get

x - 3 = 3

⇒ x = 3 + 3 = 6

∴ x = 6 and y = 3

Thus, the values of the variable are 3 and 6.

What is the shaded area of the figure?

Marta_Voda [28]

Answer:

Step-by-step explanation:

The idea here is to find the area of the circle and then subtract from it the area of the triangle. That will give you the area of what's left in the circle (the shaded part). The area of a circle is:

$A_c=\pi r^2$ so

$A_c=(3.14)(12.4)^2$ where 12.4 is the radius.

$A_c=482.81$ rounded to the nearest tenth. I used 3.14 for pi.

Now for the area of the triangle. The formula is

$A_t=\frac{1}{2}bh$ where h is the height of 12.4 and the base is the diameter which is 12.4 * 2 = 24.8

$A_t=\frac{1}{2}(24.8)(12.4)$ so

$A_t=153.76$

Now subtract the triangle's area from the circle's area:

482.81 - 153.76 = 329.05 mm²

Janet has a square piece of cloth. She cuts 3 inches off of the length of the square and 3 inches off of the width. The area of

vesna_86 [32]

Let the side length of the original square be x, then

1/4 x^2 = (x - 3)^2

x^2 = 4(x^2 - 6x + 9) = 4x^2 - 24x + 36

3x^2 - 24x + 36 = 0

3(x^2 - 8x + 12) = 0

x^2 - 8x + 12 = 0

x^2 - 2x - 6x + 12 = 0

x(x - 2) - 6(x - 2) = 0

(x - 6)(x - 2) = 0

x - 6 = 0 or x - 2 = 0

x = 6 or x = 2

therefore, the side length of the original square is 6 inches.

Hope this helps!
