Answer:
D. 3(x+2) can be rewritten as 3x + 6 using the distributive property
Step-by-step explanation:
Given
![3(x + 2) = 3x + 6](https://tex.z-dn.net/?f=3%28x%20%2B%202%29%20%3D%203x%20%2B%206)
Required
Explain
From the list of given options, option D answers the question.
This is because, the expression above involves distributive property and only option D correctly states that.
A distributive property is:
![a*(b + c) = a*b + a * c](https://tex.z-dn.net/?f=a%2A%28b%20%2B%20c%29%20%3D%20a%2Ab%20%2B%20a%20%2A%20c)
In this case:
and ![c = 2](https://tex.z-dn.net/?f=c%20%3D%202)
So:
![a*(b + c) = a*b + a * c](https://tex.z-dn.net/?f=a%2A%28b%20%2B%20c%29%20%3D%20a%2Ab%20%2B%20a%20%2A%20c)
Substitute values for a, b and c
![3*(x + 2) = 3 * x + 3 * 2](https://tex.z-dn.net/?f=3%2A%28x%20%2B%202%29%20%3D%203%20%2A%20x%20%2B%203%20%2A%202)
![3(x + 2) = 3x + 6](https://tex.z-dn.net/?f=3%28x%20%2B%202%29%20%3D%203x%20%2B%206)
B : 30
95+55 = 150
180-150 = 30
