Answer:

Step-by-step explanation:
we know that
The volume of a rectangular prism is equal to
-----> equation A
where
L is the length
W is the width
H is the height
we know that
-----> equation B
----> equation C
substitute equation B and equation C in equation A
Apply distributive property

Answer:
3.6
Step-by-step explanation:
Using the area of rectangle formula L*W= A
we can plug in our known values
20*w=72
then we can divide 20 on both sides giving us 3.6 inches for width.
Step-by-step explanation:
H(x)=

If g(x) values =0, h(x) will be undefined.
So f(x)=0, h(x) will be undefined.
Zo find values of f(x) equal 0.
That is when x=2. So the answer to first solution is 2.
h(x) is negative when (-oo, -3) U (2,oo)
Answer:
Step-by-step explanation:
Money left Rs. 800
Money spent = 75%
- Rs 800 = 25%
- 800 = 0.25x
- x = 800/0.25
- x = 3200
Initial amount was Rs. 3200
