I got 3/8, hope this helps.
Answer:
the complete question in the attached figure
we have that
f(x)=3x/(4x²-4)
we know that
the denominator can not be zero
so
(4x²-4)=0
4x²=4
x²=1----> x=(+/-)√1
x1=1
x2=-1
the values of x=1 and x= -1 make the denominator zero, therefore they do not belong to the domain of the function
the answer is
the domain of the function is all real numbers except 1 and -1
V=L X W X H
1,296=6 x w x 24
1,296=144 x w
1296/144=w
9=width
the answer to this question is -8
Do 1/3 x 7 (due to the parentheses which mean multiplication). Once you get that answer you should have 8/9 = x + (answer). Now subtract that answer from 8/9 and that's your x!
