The point(-3,3) is successively reflected across the x-axis, then y-axis and then x axis again. what is the area of the square formed by these 4 points?

36

Step-by-step explanation:

Plot all the points

(-3,3) reflected across the x axis would give you (-3,-3). (-3,-3) reflected across the y axis would give you (3,-3) and then reflected across the x axis again would give you (3,3)

Plot

(-3,3)

(-3,-3)

(3,-3)

(3,3)

Draw the perimeter of a square connecting the points.

Count the units from left to right and top to bottom.

Both are 6 units since it is a square.

You have found the length and width, so multiple them to get the area.

L×W= Area

6×6= 36

36 is the area of the box.

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
