Answer:
1B , 2B , 3 Output = 2*input + 1
Step-by-step explanation:
1. given (3n + 5) * 2
first do the operation between brackets.
n=5 so (3*5) =15 which gives (15 + 5)=20
now finish with the operation after the brackets, which is multiply by 2. 20*2 = 40, which is answer B.
2. 3x means 3*x which means in words: 3 times the number, which is answer A.
3. From the tabe you can see that if you just multiply the input by 2, you are almost at the output. If you add 1 then it is perfect..So you get Output = 2*input + 1
