Answer: Equivalent expression would be 9e-3.
Step-by-step explanation:
Since we have given that
As we need to simplify the above expression:
First we open the brackets :
Now, add it to 6e.
So, it becomes,
Hence, equivalent expression would be 9e-3.
6e + 3(e - 1)
6e + 3e - 3
9e - 3
No, the number 2140 will not be in the sequence because it cannot be obtained by adding 40 repeatedly.
To determine this, check if the number 2140 can be obtained by adding 40 repeatedly to any of the given numbers in the sequence (40, 80, 120, 160, 209).
To do this, find the remainder when dividing 2140 by 40:
2140 ÷ 40 = 53 with a remainder of 20
Since the remainder is not 0, we know that 2140 cannot be obtained by adding 40 repeatedly to any of the given numbers. Therefore, the number 2140 will not be in the sequence.
