Answer: x=12
First, you do 8 squared = 4(4+x)
Then, you distribute and becomes a two-step equation.
64=16+4x.
So x=12.

Well first you need to show the rest of the problems before i can truely help you sorry.
Answer:
1.
Step-by-step explanation:
Note that 2^4 - 2^3 = 16 - 8 = 8 = 2^3
In a similar way 2^6 - 2^5 = 64 - 32 = 32 = 2^5.
So 2^99 - 2^98 = 2^98 , 2^98 - 2^97 = 2^97 , 2^97 - 2^96 = 2^96 and so on.
Therefore when we come to the last 2 terms we have 2^1 - 2^0 = 2 - 1
= 1 , so the answer is 1.
