The answer you are looking for is associative property of addition.
In associative property, no matter where the parenthesis are, a + (b + c) is going to be equal to (a + b) + c. Since the parenthesis follow the equation a + (b + c) = (a + b) + c, you can assume you are using the associative property. Lastly, add "of addition" to associative property, since you are using addition, not multiplication.
I hope this helps!

Step-by-step explanation:
8 grams reduced by 30%....if it is reduced by 30%, then there is a total of 70%
70% of 8.....turn ur percent to a decimal..." of " means multiply
0.70 * 8 = 5.6 grams <==
10 grams reduced by 40%.....so it contains 60%
60% of 10 =
0.60 * 10 =
6 grams <==
so brand A, the 8 grams reduced by 30%, now has less fat <==
A range of 2 reveals that the smallest and largest data values are 2 units away from each other.
<h3>What does the range reveal?</h3>

Answer:
96
Step-by-step explanation:
commom difference = d
a₆ + a₇ = 16
a₅ + a₈ = (a₆ - d) + (a₇ + d) = a₆ + a₇ = 16
a₄ + a₉ = (a₆ - 2d) + (a₇ + 2d) = a₆ + a₇ = 16
Similarly,
a₃ + a₁₀ = 16, a₂ + a₁₁ = 16, a₁ + a₁₂ = 16
so
a₁ + a₂ + ... + a₁₁ + a₁₂ = 6 x 16 = 96
