Step-by-step explanation:
3x + 4 < -7
3x < -7 - 4
3x < -11
x < -11/3 ≈ -3,666
x = {3,2,1,0, etc}
The surface area of the figure will be 88 square feet.
<h3>
What is Geometry?</h3>
Geometry deals with the size of geometry, region, and density of the different forms both 2D and 3D.
The surface area can be found by the sum of all the parts of the figure.
Therefore,
Surface area = 8 + 8 + 12 + 12 + 24 + 24
Surface area = 88
The surface area of the figure will be 88 square feet.

Answer: m=0
Step-by-step explanation:
The amount of the radioactive substance is 374.6 g
<h3>How to determine the amount of
radioactive substance?</h3>
The given parameters are:
- Initial, a = 424 mg
- Rate, r = 6%
- Time, t = 2 hours
The amount of the radioactive substance is calculated as:
A(t) = a(1 - r)^t
This gives
A(t) = 424 * (1 - 6%)^t
At 2 hours, we have:
A(2) = 424 * (1 - 6%)^2
Evaluate
A(2) = 374.6
Hence, the amount of the radioactive substance is 374.6 g
