(13 + 5) + 5 = 23 choose an equivalent addition sentence that shows the associative property of addition. a. (13 + 5) + 5 = 23 b. 23 = (13 + 5) + 5 c. 13 + 5 + 5 = 23 d. 13 + (5 + 5) = 23

For this case we have that, by definition, the associative property establishes that:

So, if we have:

According to the property mentioned above, we have equivalently:

Option D

7.25

step-by-step explanation:

we know that 7 equals to 7.0. we also know that 1/4=0.25. so we can add the two together and we get 7.25

other answer is correct. i had used the radius of the radius somehow. a website:
