Given: B is the midpoint of segment AC. AB = 3x - 1, BC = x +7 Find: The length of segment AC
22
02
011

hope it helps

plz mark as brainliest

22

Step-by-step explanation:

Given B is the midpoint of AC , then

AB = BC , substitute values

3x - 1 = x + 7 ( subtract x from both sides )

2x - 1 = 7 ( add 1 to both sides )

2x = 8 ( divide both sides by 2 )

x = 4

Thus

AC = AB + BC = 3x - 1 + x + 7 = 4x + 6 = 4(4) + 6 = 16 + 6 = 22

none cuz there are no "following statements" regarding the question

step-by-step explanation:

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.
