Any math experts in geometry on thx

green box= b

grey box = a

Step-by-step explanation:

They are asking for the distance formula for RS.

d = √(x2-x1)² +(y2-y1)²

(0,a) is x1, y1

(b,c) is x2, y2

d= √(b-0)² + (c-a)²

d = √(b)² + (c-a)²

hi there!

the answer to this question is d: 35

step-by-step explanation:

5 to the power of 2 is 25

2 multiplied by 5 is 10

then you add the 2 numbers and you get 35

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.
