What is the following product? (x StartRoot 7 EndRoot minus 3 StartRoot 8 EndRoot) (x StartRoot 7 EndRoot minus 3 StartRoot 8 EndRoot)
7 x squared + 72
7 x squared minus 12 x StartRoot 14 EndRoot + 72
7 x squared minus 12 x StartRoot 14 EndRoot minus 72
7 x squared minus 72

207/8 is the right

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.

final total: 63

step-by-step explanation:

60 times sales tax

60 times 0.05

3

60 + 3

63

so the possibilities of the measurement of the side of the triangle are either it is longest side or not the longest side

when it is the longest side

s < 25 + 35s < 60

if it is not the longest side

35 < 25 + s10 < sso 10 < s < 60so the perimeter70 < p < 130
