Answer:
384 inches²
Step-by-step explanation:
The surface area of a cube is found by using 6a².
6 = the number of sides in a cube
a = the given dimension (in this case, 8 inches long)
SA = (6)8²
SA = 6(64)
SA = 384

What are equations?</h3>
- A mathematical equation is a formula that uses the equals sign to represent the equality of two expressions.
- a formula that expresses the connection between two expressions on each side of a sign.
- Typically, it has a single variable and an equal sign.
- Like this: 2x - 4 Equals 2.
- In the above example, the variable x exists.
So, the equation of depreciation: y = A(1 - r)∧t
The current value is y.
A is the initial cost.
r is the depreciation rate.
t is the time in years, and
In four years, we must ascertain the present value.
Now,
y = $24000(1 - 0.15)⁴
y = 24000(0.85)⁴
y = 24000 × 0.52200625
y = 12528.15
Therefore, with the help of the given equation, we know that the automobile is worth $12528.15 after four years.

Complete question:
The general equation for depreciation is given by y = A(1 – r)t, where y = current value, A = original cost, r = rate of depreciation, and t = time, in years. The original value of a car is $24,000. It depreciates 15% annually. What is its value in 4 years? $
Answer:
24 m³
Step-by-step explanation:
We need to find the volume of the prism. Given that , rectangular prism with cubic units arranged in two rows of two with six total layers . And the volume of each unit is 1 m³ .
<u>Volume</u><u> of</u><u> </u><u>one</u><u> </u><u>unit </u><u>:</u><u>-</u><u> </u>
<u>By </u><u>Unitary</u><u> Method</u><u> </u><u>:</u><u>-</u><u> </u>
Volume of two cubes , will be :-
<u>Volume</u><u> of</u><u> </u><u>one </u><u>layer </u><u>:</u><u>-</u><u> </u>
<u>Volume</u><u> of</u><u> </u><u>six </u><u>layers </u><u>:</u><u>-</u><u> </u>

Answer:
im pretty sure #9 is just y=7x... it should be parallel with y=7x-3 since it has y intercept of 0 rather than -3.
