What is a simplified expression for the perimeter of the polygon?
a polygon has 6 uneven sides with side lengths: 6 x + 2 y, y squared, 6 x + 2 y, y squared, 4 x squared, and x squared + y.

the 4th choice is the correct one

step-by-step explanation:

i need more info. are you looked to see there mph? how much they deliver? how far they go?

step-by-step explanation:

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled

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.
