Question

I don't understand this question can someone help me with this please, please explain!! and thank you for the help!! If u dont know try your best :D

Answer 1

B) (8 x 20) - (8 x 1)

D) (2 x 9) + (2 x 3)

Explanation:

Distributive Property: "The distributive property tells us how to solve expressions in the form of a(b + c)."

___________________

Step 1: 8 x 19 = 152

Using PEMDAS, you can see which order to solve the equations in.

PEMDAS tells us to solve whatever is within the parenthesis first but there are 2 parenthesis and both have multiplication so just solve the first parenthesis first;

8 x 20 = 160

Step 2: We now have to solve the second parenthesis;

8 x 1 = 8

Step 3: Using PEMDAS, we see that after we solve the parenthesis, we do subtraction. So subtract 8 from 160.

160 - 8 = 152

So your answer is B) (8 x 20) - (8 x 1).

___________________

Step 1: 2(9 + 3)

Using the Distributive property, we multiply 2 by 9 and 3;

2 x 9 = 18

2 x 3 = 6

Now you are left with 18 + 6.

18 + 6 = 24

So your answer is D) (2 x 9) + (2 x 3).

Hope this Helps! :)

Answer 2

Question 1 : B) (8 x 20) - (8 x 1)

Question 2 : D) (2 x 9) + (2 x 3)

Explanation:

Distributive Property is used in algebraic expressions, to divide the equation, to make it easier to solve. For question 1, since it was 20, you must subtract 8 from that answer, because 20 is 1 more than 19. For question 2, (2 x 9) + (2 x 3) would be the same thing as 2(9+3).
