Answer:
2x + 12
Step-by-step explanation:
Example of Associative Property Addition:
a + (b+c) = b + (a+c)
Now, implement it to the given expression:
(2x+8) + 4 = 2x + (8+4)
That simplifies to:
2x + 12
Answer:
2 (3 - 7 r)
Step-by-step explanation:
Simplify the following:
-4 (3 r - 2) - 2 (r + 1)
-4 (3 r - 2) = 8 - 12 r:
8 - 12 r - 2 (r + 1)
-2 (r + 1) = -2 r - 2:
-12 r + -2 r - 2 + 8
Grouping like terms, -2 r - 12 r - 2 + 8 = (8 - 2) + (-12 r - 2 r):
(8 - 2) + (-12 r - 2 r)
-12 r - 2 r = -14 r:
-14 r + (8 - 2)
8 - 2 = 6:
6 - 14 r
Factor 2 out of 6 - 14 r:
Answer: 2 (3 - 7 r)
