this is the correct way to solve these types of exercises
then we will try to do the same where a is (6+9x) and b is 24

and solve the right inequality for x

subtract 6 for all expression

now divide on 9

ok, this means that the x values will be from -10/3 to 2 including these
Graph
solution is the red zone
Step-by-step explanation:
2^(2x) - 5(2^x) = -4
(2^x)^2 - 5(2^x) = -4
Substitute 2^x = z --> x = ln(z)/ln(2)
z^2 - 5z = -4
z^2 - 5z + 4 = 0
(z - 1)(z - 4) = 0
z = 1 --> x = ln(1)/ln(2) = 0
z = 4 --> x = ln(4)/ln(2) = 2
Answer: B. 140 cubic inches.
Step-by-step explanation:
The question is asking you to find the volume of the rectangular prism.
You can find this by using this formula:

Where w is the width, h is the height, and l is the length.
Substitute the sides of the rectangular prism into the equation:

The volume of the prism is 140 cubic inches.
The correct answer is B.
I think x should equal -2 or -3
