Answer:
w = 4.5 in
Step-by-step explanation:
V = lwh
138.24 = 9.6(3.2)w = 30.72w
w = 4.5 in
Okay, here we have this:
Considering the provided expression, we are going to analize which exponential expression is equivalent, so we obtain the following:
As the property of the exponent of a multiplication says that it is equal to the product of each number raised to that power. We have this:

Finally we obtain that the correct answer is the option D.
Answer:
17
Step-by-step explanation:
since it is in the middle you can just divide by 3 since one will be greater and one will be less so 51/3=17
Let width of the floor be x feet, them area is
x(x+2) = 168
x^2 + 2x - 168 = 0
(x - 12)(x + 14) - 0
so x = 12
the floor is 12 ft by 10 ft
the width of the rug should be 10 - 2(2) = 6 feet
If you’re looking for x it would be -4/3
