Re write it in so that to have one single entity on the left & same on the right
log(x-1)-log5 = log[(x-1)/5]
and log(x+1)-logx = log[(x+1)/x]
So:
log[(x-1)/5] = log[(x+1)/x] ==> (x-1)/5 = (x+1)/x
Now you can solve it: x(x-1)=5(x+1)
==> x² - 6x -5 =0
Solving this quadratic equation gives x'=3+√14 & x" =3-√14
Answer:
Step-by-step explanation:
If f(x)=x+1 and g(x)=2x then
g(f(x))=2(x+1)
g(f(x))=2x+2
Well to get the area of 288 the dimensions would be a couple of things but 16 ft by 18 ft seems to work, so the dimensions increase by 4 ft on each side.
12+4=16
14+4=18
18*16=288
The answer to this is y=5
9.8, square root of 109, square root of 128
