Line equation is
y - y1 = m * (x - x1)
y - (-7) = (-5) * ( x - 1)
y + 7 = -5x + 5
y + 5x + 2 = 0
For this case we have by definition, that the total surface area of a regular pyramid with a square base is given by:

Where:
p: It is the perimeter of the base
S: It's the inclination
It is the area of the base
Substituting:

ANswer:
Option B
It seems like there's a typo? The x and y rows are identical
Assuming there is no typo, then the input and the output are the same. Meaning that whatever you plug in, is what comes out. If the output is 40, then the input must be 40.
So the answer is 40 (assuming there are no typos made by your textbook or teacher)
Answer:
Angles KNL and JNM are vertical angles so they are equal so
10y - 12 = 8y + 4
2y = 16
y = 8
So angle KNL = 10y - 12 = 10(8) - 12 = 80 - 12 = 68�
and, as a check
Angle JNM = 8y + 4 = 8(8) + 4 = 64 + 4 = 68�
Step-by-step explanation:
Answer:
64 square ft^3
Step-by-step explanation:
If the side lengh is 3 then you would have 4^3 which is 64.
