Answer:
Step-by-step explanation:
In the first pattern, there were 6 sticks
In the second pattern, there were 10 sticks.
In the third pattern, there were 14 sticks.
Based on the pattern, we see that each time, 4 more sticks are added and that the initial amount of stick is 6.
Thus: the equation for how many sticks there would be in pattern n is:
# of sticks in pattern n = 6 + 4n

Answer:
c=3
Step-by-step explanation:
First simplify like terms.
1+4c=7+2c
1+2c=7 (subtract 2c from both sides)
2c=6 (subtract 1 from both sides)
c=3 (divide by 2)
CHECK:
1+4(3)=7+2(3)
1+12=7+6
13=13
Yes!
