Answer: B. ![3+(1+11)=15](https://tex.z-dn.net/?f=3%2B%281%2B11%29%3D15)
Step-by-step explanation:
1. By definition, the associative property of addition is:
![(a+b)+c=a+(b+c)](https://tex.z-dn.net/?f=%28a%2Bb%29%2Bc%3Da%2B%28b%2Bc%29)
2. Therefore, if you have the following expression:
![(3+1)+11=15](https://tex.z-dn.net/?f=%283%2B1%29%2B11%3D15)
You apply the Asociative property of addition by regrouping the numbers as following:
![3+(1+11)=15](https://tex.z-dn.net/?f=3%2B%281%2B11%29%3D15)
3. Then, you can conclude that the correct option is B.
![\tt \: 4(x + 6) \leqslant - 56](https://tex.z-dn.net/?f=%20%5Ctt%20%5C%3A%204%28x%20%2B%206%29%20%5Cleqslant%20%20-%2056)
Divide both sides of the inequality by 4
![\sf \: x + 6 \leqslant - 14](https://tex.z-dn.net/?f=%20%5Csf%20%5C%3A%20x%20%2B%206%20%5Cleqslant%20%20-%2014)
Move the constant to the right-hand side and change its sign
![\bf \: x \leqslant - 14 - 6](https://tex.z-dn.net/?f=%20%20%5Cbf%20%5C%3A%20x%20%5Cleqslant%20%20-%2014%20-%206)
Calculate the difference
![\rm \: x \leqslant - 20](https://tex.z-dn.net/?f=%20%5Crm%20%5C%3A%20x%20%5Cleqslant%20%20-%2020)
And we are done solving!!~
Hey there!
m(4 + 7)
= 1m(4 + 7)
DISTRIBUTE m WITHIN the PARENTHESES
= m(4) + m(7)
= 4(m) + 7(m)
= 4(1m) + 7(1m)
= 4m + 7m
COMBINE the LIKE TERMS
= 11m
Therefore, your answer is: 11m
Good luck on your assignment & enjoy your day!
