To find the area of parallelogram rstu, juan starts by drawing a rectangle around it. each vertex of parallelogram rstu is on a side of the rectangle he draws. on a coordinate plane, parallelogram r s t u has points (negative 4, negative 3,) (negative 5, 1), (4, 3), and (5, negative 1). which expression can be subtracted from the area of the rectangle to find the area of parallelogram rstu? 2 (18 + 4) one-half (18 + 4) (18 + 4) (18 - 4)

y=mx+b

step-by-step explanation:

m slope, b y-intercept

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.
