Commutative property (when dealing with addition) means that you can change the order of the terms without changing the sum, so you could write
y + 3x
hope this helps :)
Answer: OPTION D
Step-by-step explanation:
To solve this problem you must apply the formula for calculate the surface area of the rectangular prism:

Where w is the width, h is the heigh and l is the lenght.
Based on the rectangular prism shown, you have that:

Finally when you substitute values into the formula you obtain the following result:
![SA=2[(9.08cm*3.23cm)+(11.73cm*9.08cm)+(11.73cm*3.23cm)]=347.45cm^2](https://tex.z-dn.net/?f=SA%3D2%5B%289.08cm%2A3.23cm%29%2B%2811.73cm%2A9.08cm%29%2B%2811.73cm%2A3.23cm%29%5D%3D347.45cm%5E2)
I can’t see the questions
F(x) = -x + 4
Substitute x = -2 to the equation:
f(-2) = -(-2) + 4 = 2 + 4 = 6
Answer: A) 6
