2 (6 x+6)= ?
12 x+ 12=
12 x= -12
x= -1
So first you take what is outside the "( )" and you multiply it with what's in the "( )" so that gave us 12 because 2*6= 12.
The nth term is given by 2ⁿ-1.
The series looks like, 1, 3, 7, 15, 31, 63, 127, ...
Replace the f(x) in the second equation will 6x + 5 so then it looks like 2(6x + 5) + 6. Then distribute so it’s 12x + 10 + 6 and then simplify to 12x + 16
Answer:
120
Step-by-step explanation:
Just add the 20 back to 40 and times by 2
40 + 20 = 60
60 * 2 = 120
