ANSWER: -252
HOW TO GET IT:
Simply follow PEMDAS. Solve each exponent first, then do the rest.
Answer:
9 x (6+x) = 1
Step-by-step explanation:
<u>1. </u>Subtract 24 from both sides
-3x = -27 - 24
Simplify -27 - 24 to -51
-3x = -51
Divide both sides by -3
x = -51/-3
Two negatives make a positive
x = 51/3
Simplify 51/3 to 17
<u>x = 17</u>
<u>2.</u> Regroup terms
n/5 - 17 = 33
Add 17 to both sides
n/5 = 33 + 17
Simplify 33 + 17 to 50
n/5 = 50
Multiply both sides by 5
n = 50 * 5
Simplify 50 * 5 to 250
<u>n = 250</u>
Answer:
f(n) = 2 * f(n - 1) + 1
Step-by-step explanation:
First, notice that the difference between each neighboring term is different, so it is not linear, so we can rule out A and B. Now, it's all about finding a pattern. Eventually, through guess and check, you will get 2 * f(n - 1) + 1.
Perhaps there was a typo in C? Idk!!
