Find the value of X 11x-2 19x+3 9x+1 PLEASE LOOK AT PICTURE

x=4

Step-by-step explanation:

1) first write it down --> 11x-2+9x+1=19x+3

2) then combine like terms on the left side of the equation. --> 20x-1=19x+3

3) Then subract 19x on both sides --> x-1=3

4) After add 1 to both sides --> x=4

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3

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.
