Ineed in pre-algebra.
i need to practice this and it needs to to be solved in distributive property
2 (x +4) - 10 = 12
i'm not sure what i'm supposed to do with the - 10, can someone ?

2(x + 4) - 10 = 12

Because - 10 is outside of the parentheses and away from the coefficient, it will be ignored for right now.

To apply the distributive property, multiply the coefficient (2) by each term in the parentheses (x) and (4)

2x + 8 - 10 = 12 is the simplified equation after applying the distributive property.

Now, we can simplify.

2x - 2 = 12

Add 2 to both sides.

2x = 14

Divide both sides by 2.

Your answer is x=7. You use distributive property for the 2(x+4) and add 10 to the other side.

Step-by-step explanation:

2(x+4) - 10 = 12

First add 10 to the other side

2(x+4) = 22

Multiply 2 by (x+4)

2 times x is 2x

2 times 4 is 8

so you have 2x + 8 = 22

now subtract 8 from both sides

2x = 14

x=7

your answer is the last one

step-by-step explanation:

divide the length of a'c' by the length of ac to get a scale factor of two

& then reflect vertically (over the y-axis)

so your answer is dilation by a scale factor of 2 followed by reflection over the y-axis

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.
