Write x2 − 6x + 7 = 0 in the form (x − a)2 = b, where a and b are integers. (1 point)
(x − 4)2 = 3
(x − 3)2 = 2
(x − 2)2 = 1
(x − 1)2 = 4

B. .  

Step-by-step explanation:

We have been given an equation . We are asked to write our given expression in form .

First of all, we will subtract 7 from both sides of our given equation.

Now, we will complete the square for left side of equation by adding the half the square of 6.

Upon adding 9 on both sides of our equation, we will get:

Therefore, our required equation would be and option B is the correct choice.

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.
