The length of side PQ of the polygon is 7 units

Step-by-step explanation:

Given points are:

P(5, 4) and Q(−2, 4)

In order to find the length of PQ, the distance formula for coordinate geometry will be used.

The distance formula is given by:

$d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2$

Here

(x1,y1) = (5,4)

(x2,y2) = (-2,4)

$PQ = \sqrt{(-2-5)^2+(4-4)^2}\\=\sqrt{(-7)^2+(0)^2}\\= \sqrt{49}\\= 7\ units$

Hence,

The length of side PQ of the polygon is 7 units

When u have 2 negatives it will always make a positive -(-)

-15 + 8 + 23 - 46

-7 + 23 - 46

16 - 46

-30

Given that the diameter of Circle A is 6 cm , and the radius of Circle B is 18 cm , what can be concluded about the two circles?

ELEN [110]

Answer:

The radius of circle B is 6 times greater than the radius of circle A

The area of circle B is 36 times greater than the area of circle A

Step-by-step explanation:

we have

Circle A

$D=6\ cm$

The radius of circle A is

$r=6/2=3\ cm$ -----> the radius is half the diameter

Circle B

$r=18\ cm$

Compare the radius of both circles

$3\ cm< 18\ cm$

$18=6(3)$

The radius of circle B is six times greater than the radius of circle A

Remember that , if two figures are similar, then the ratio of its areas is equal to the scale factor squared

All circles are similar

In this problem the scale factor is 6

$6^{2}=36$

therefore

The area of circle B is 36 times greater than the area of circle A
