Distribute the -2.5 to 4X and -3
It should look like -2.5 x 4X and -2.5 x -3(the answer for -3 should be positive)

Answer:

we will use democracy so that everyone gets a say in what happens to the colony, second the government will make the decisions and the people will provide options and different ideas, and i believe its the best type because everyone has a say in what happens and the government isn't too powerful and has as much power as the people do.

Find the missing measures for the rectangle. l = _?_ w = 4.2 m A = 37.8 m2 P = _?_ A) 9 m; 26.4 m B) 14.7 m; 61.74 m C) 9 m; 13.

egoroff_w [7]

Answer:

The correct answer is A.

Step-by-step explanation:

The area of a rectangle can be calculated using the following formula:

$Ar=W . I$

If we know that the area measures $37.8 m^{2}$ and one side of the figure measures 4.2 m, we can say that:

$37.8m^{2}=4.2m. I$

We isolate the side we don't know:

$\frac{37.8m^{2}}{4.2m} = I\\9 m = I$

So I = 9 m

To know the perimter of a rectangle, we use the following formula:

$P= I. 2 + W . 2$

$P= 9m. 2 + 4.2m. 2$

$P= 26.4 m$

PLEASEEE HURRYYY

Masteriza [31]

Answer:

(2,-5) and (2,1).

Step-by-step explanation:

We need to find the find all the points having an x coordinate of 2 whose distance from the point (-2,-4) is 5.

A circle with center (-2,-4) and radius 5 represents all the points whose distance from the point (-2,-4) is 5.

Standard form of a circle is

$(x-h)^2+(y-k)^2=r^2$

where, (h,k) is center and r is the radius.

$(x-(-2))^2+(y-(-4))^2=(5)^2$

$(x+2)^2+(y+2)^2=25$

Now, put x=2.

$(2+2)^2+(y+2)^2=25$

$(4)^2+(y+2)^2=25$

$(y+2)^2=25-16$

$(y+2)^2=9$

Taking square root on both sides.

$y+2=\pm\sqrt{9}$

$y+2=\pm3$

$y+2=-3\text{ or }y+2=3$

$y=-5\text{ or }y=1$

So, the y-coordinates of the points are -5 and 1.

Therefore, the required points are (2,-5) and (2,1).

Darina [25.2K]

12x2= $24
24+28+45= $97

So $97 is 100%

So 100%-30% =70% (30% off)
(note: 70% = 70/100 = 0.7)

97 x 0.7 = $67.90
