Answer:
Division is not commutative because 25÷5 does not equal 5÷25
Step-by-step explanation:
The surface area of a sphere is
where r is the radius;
The circumference is
so that
using this value we can evaluate the surface area of 1 ball as:
For 100 ball you get:
I believe the answer is d but tell me if I’m wrong

Answer: 15+2x</h3>
=======================================
The commutative property of addition is where we can add two numbers in any order we want. Example: 2+3 = 5 and 3+2 = 5.
In general, the rule is x+y = y+x.
In our case, 2x and 15 can be added in any order. So that's why 2x+15 is the same as 15+2x.
-------
Side note: a similar rule applies for multiplication as well. This is called the commutative property of multiplication. Example: 9*3 = 27 and 3*9 = 27. So we can say x*y = y*x.
