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)
Answer:
56n - 35
Step-by-step explanation:
6n + 5(10n - 7) ← multiply each term in the parenthesis by 5
= 6n + 50n - 35 ← collect like terms
= 56n - 35
Answer:
The correct answer is Dale is absolutely wrong.
Step-by-step explanation:
When the cake was complete, it had 360°. When the cake is divided into four halves each half now has 90° each.
Three person including Dale is about to eat the one fourth of the cake, divided among them equally.
Thus each friend gets
° = 30° of cake each.
But Dale claims that each piece of cake has an angle measure if 45°, which is a contradiction as each piece is supposed to to be equal.
Thus Dale is WRONG.
