Answer:
-1/2
Step-by-step explanation:
- x^2- 16^x = 0
- x^2 = 16^x
- x^2 = 4^2x
- x = 4^x
- logx = xlog4
- 1/x×logx = log4
- log(x^1/x) = log4
- x^(1/x) = 4
At this point you can guess and try. And it seems that x = -1/2, lets check:
- (-1/2)^(1 /-1/2)= (-1/2)^-2= 2^2= 4
So, this is correct: x= -1/2
X=6 and x=-8
To solve this, you would treat x-6=0 as one equation, you add 6 to each side to get rid of -6, hence you would get x=6.
Same goes for x+8=0, subtract 8 from each side to get rid of the +8, then you get x=-8
Answer:
36 feet long.
Step-by-step explanation:
If the longest wall in the living room is referring to the side that I have drawn over in white and red in the attached image, or if it is the leftmost wall, then that wall is 36 feet long. For every half inch, it is 6 feet, so because there are 6 'half inches' in 3, you multiply 6 feet by the 6 half inches there are, and get 36. There are simpler ways to solve it but I can't take a picture of my work, so I hope this helps. Good luck.
