4z 27 +x5 y14 if x, y and z each represent a different digit from 0 to 9, what is the value of (x)(y)(z)?

4(1)(2) = 8

Step-by-step explanation:

Consider the addition in the unit digits.

z +7 + 5 = z + 12

and the unit digit of this sum should be 4 since the unit digit of the answer is 4.

Also, since z is a number from 0 to 9, the only possibility is z = 2.

Hence, the unit digit sum is 14 and the carry over is 1.

Now, consider the tenth digits sum with previous carry over 1.

1 + 4 + 2 + x = y1

7 + x = y1

Since, x and y are numbers from 0 to 9, the only possibility is x = 4 and hence

7 + 4 = y1

11 = y1

y = 1

So, x = 4, y = 1, z = 2

(x)(y)(z) = (4)(1)(2) = 8

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.
