Answer:
A. 
Step-by-step explanation:
This is a great question! The first thing we want to do here is to take the constant out of the expression, in this case 5. Doing so we would receive the following expression -
We can then apply the power rule " 
", where a = exponent ( in this case 4 ),
From now onward just simplify the expression as one would normally, and afterward add a constant ( C ) to the solution -
- Add the exponents,
- 5 & 5 cancel each other out,
- And now adding the constant we see that our solution is option a!
Get all the n together so 3n+2n=5n
5n-17=38
Minus 17 from both sides
5n= 55
N= 11
Answer:
84
Step-by-step explanation:
2^2=4
4 + 8=12
12 times 7= 84
-4/7 > -2
greater then goes to the right and less then goes to the left
-4/7 is located to the right of -2
