To find the slope of the expression:

We need to remember that this is the Slope-intercept Form of the line equation:

Where
m = slope
b is the y-intercept.
Therefore, the slope of the line equation above is m = 3.
Answer:
6
Step-by-step explanation:
2x + 3 = 15
- 3 -3
__________
2x = 12
_______
2 2
That cancels out 2x so x = 6
Answer:
= 868.1ft^3
Step-by-step explanation:
Volume of the square based pyramid = BH/3
B is the base area
H is the height of the pyramid
Base area = Length * Length
Base area = 14.1*14.1
BAse area = 198.81ft^2
Height = 13.1feet
Substitute
Volume = 198.81*13.1/3
Volume of the pyramid = 868.1ft^3
Hence the volume of a pyramid with the square base is 868.1ft^3
so it would be 8x13/8+13, which would simplify out to be 104/8+13 which would then simplify out even more to be 104/21 as a fraction or 4.95 as a decimal
