Answer:
12x − 2
Step-by-step explanation:
7(x+4)+5(x−6)
Distribute:
=(7)(x) + (7)(4) + (5)(x) + (5)(−6)
=7x + 28 + 5x − 30
Combine Like Terms:
=7x + 28 + 5x − 30
=(7x+5x) + (28−30)
= 12x − 2
Answer:
The first 3 terms of the sequence
are:

Step-by-step explanation:
Given the sequence
Here
represents any term number in the sequence
Determining the first term

Determining the 2nd term
substitute n = 2 in the sequence to determine the 2nd term




Determining the 3rd term
substitute n = 3 in the sequence to determine the 3rd term




Therefore, the first 3 terms of the sequence
are:
