Which steps show how to use the distributive property to evaluate 7 x32?
A. 7(32) = 7(30 + 2) = 7.30 + 30 - 2 = 210 + 60 = 270
B. 7(32) = 7(30 + 2) = 7.30 + 7.2 = 210 + 14 = 224
c. 7(32) = 7(30 + 2) = 7.30 – 7. 2 = 210 – 14 = 196
D. 7(32) = 7(30 + 2) = 7.30 + 2 = 210 + 2 = 212

Answers

The correct option is B, 7(32) = 7(30 + 2) = 7.30 + 7.2 = 210 + 14 = 224

plz help me with this qustion?????//

Answers

Answer:

Step-by-step explanation

When rounding, you want the number to change as little as possible. It is easier for the number to be 250 instead of 200 because 229 is closer to 250. in the same way, 3.22 is closer to 3 than 4. Now to check this, if you do 229 x 3.22, you get 737.38. Now looking at the answer choices, this is most definitely closest to 750. Given all this, I think it is safe to say D is the answer.

Hope this helps!
