Answer:
All real numbers
Step-by-step explanation:
There is 3 possible solutions to a linear equation:
- One solution -a unique x value that makes the equation true
- No solution - a false statement is given after solving without a value for x
- Infinite solution - a true statement is given after solving without a value for x
Solve using inverse operations:
4(a+2)=14-2(3-2a)
4a+8=14-6+4a
4a-4a+8=8+4a-4a
8=8
Is 8=8? Yes. Therefore this is a true statement with no value for x. Infinite solutions or all real numbers.

Answer: The total number of logs in the pile is 6.
Step-by-step explanation: Given that a stack of logs has 32 logs on the bottom layer. Each subsequent layer has 6 fewer logs than the previous layer and the top layer has two logs.
We are to find the total number of logs in the pile.
Let n represents the total number of logs in the pile.
Since each subsequent layer has 6 fewer logs then the previous layer, so the number of logs in each layer will become an ARITHMETIC sequence with
first term, a = 32 and common difference, d = -6.
We know that
the n-th term of an arithmetic sequence with first term a and common difference d is

Since there are n logs in the pile, so we get

Thus, the total number of logs in the pile is 6.
Answer:
d
Step-by-step explanation:
5>2n+11
5-11>2n
-6>2n
-6/2>n
n<or equal to -3
