- The commutative property is a number property where the answer obtained is the same no matter the position of the numbers you are multiplying together.
- Commutative property of multiplication is expressed as:
a x b = b x a
a x b x c = a x c x b = b x c x a
- Note: " . " in the question also means "x" (multiplication)
- Applying commutative property to the question:
(7/15)⋅(−11)⋅(30)
(7/15) ⋅ (−11) ⋅ (30) = (7/15) . (30) . (11)
The values interchanged are: 11 and 30. The result of the multiplication remains unchanged.
Option A is the correct answer.

Option C is correct.
Step-by-step explanation:
We are given the expression:
The value of a =5 and k = -2
Putting the values and solving
Option C is correct.
Answer: (3t-2)^2
Step-by-step explanation:
Well, multiply 9 and 4 together to get 36.
Now what factors of 36 add to 12? Well, 6 and 6, so let's rewrite this:
9t^2-6t-6t+4
Now group factor what you can:
3t(3t-2)-2(3t-2)
Now 3t and -2 both share the common factor of (3t-2) so you can rewrite it as:
(3t-2)(3t-2) which is:
(3t-2)^2.
Hope that makes sense or helps!
