45(2x+5)−4=1 drag and drop the statement that shows the solution to the equation into the box.

Given equation :  45(2x+5)−4=1

45 is in front of parenthesis (2x+5).

So, we need to multiply 45 by (2x+5).

In order to multiply 45 by (2x+5), we need to distribute 45 over (2x+5).

We get, 45*2x + 45*5 = 90x + 225.

Therefore, 45(2x+5)−4=1 equation could be written as

90x + 225 - 4 = 1   in first step.

Now, subtraccting 225-4, we get 221.

In second step 90x + 225 - 4 = 1   can be written as

90x +221 = 1.

Subtractcing 221 from both sides, we get

90x +221 -221 = 1-221.

In third step we can simplify equation to

90x = -220.

Dividing both sides by 90.

90x/90 = -220/90.

In fourth step we get equation,

x = -220/90.

On simplifying fraction -220/90, we get -22/9 and in decimal we get -2.44..

So, final answer is x= -22/9 or -2.44..

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.
