By working with the given linear equation we will see that:
a) n = (d + 2)/4
b)
- A 3-penny nail is_5/4_inches.
- A 6-penny nail is_2_inches.
- A 10-penny nail is_3_inches.
<h3>
How to solve the equation for n?</h3>
Here we have the linear equation:
d = 4n - 2
We want to solve it for n, it means that we need to isolate n in one side of the equation.
If we first add 2 in both sides of the equation, and then we divide both sides by 4, we will get:
d + 2 = 4n
(d + 2)/4 = n
That is the equation solved for n.
b) The penny size is d, and n is the length of the nail, then:
if d = 3, we have:
n = (3 + 2)/4 = 5/4
if d = 6, then:
n = (6 + 2)/4 = 2
if d = 10, then:
n = (10 + 2)/4 = 3
Thus:
- A 3-penny nail is_5/4_inches.
- A 6-penny nail is_2_inches.
- A 10-penny nail is_3_inches.

Answer:
D. The volume of square based pyramid is 1280 
Step-by-step explanation:
Given:- A square base pyramid of,
Base edge (b) =16 inches.
Height (h)= 15 inches.
To find:- Volume of the square bases pyramid=?
Solution:-
As the given pyramid is a square based pyramid, therefore the formula to find the volume for square based pyramid is,
Volume of square based pyramid = 
where, b is the base edge and h is the height of the pyramid.
Volume of square based pyramid = 
Volume of square based pyramid = 
Volume of square based pyramid = 
Volume of square based pyramid = 1280
Therefore the volume of square based pyramid is 1280
