Use the GCF and the distributive property to express the sum of the product 45+15

15*(3 + 1)

Step-by-step explanation:

Greatest Common Factor (GCF) and Distributive Property

To find the GCF of two quantities, we find their prime factors:

45 = 3 * 3 * 5

15 = 3 * 5

We take the common factors 3*5=15. The GCF is 15.

We want to rewrite the expression

That is equivalent to

Note we used the GCF in each term. Now we use the distributive property to factor the 15 out of the expression:

Of course, it can be further simplified and operated, but we have rewritten the expression as required.

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer

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.
