where
B is the area of the base of the pyramid
h is the height of the pyramid
Find the area of the base B

we have

substitute the values

Answer:
(4, 2)
Step-by-step explanation:
Start by combining the equations
2x + 2x = 4X
4y - 4y = 0
16 + 0 = 16
4x = 16
x = 4
Now that you have one variable plug it back in to one of the original equations
2(4) + 4y = 16
8 + 4y = 16
4y = 8
y = 2
(4, 2)
1,770,000
find the first part of the equation (2200000) and then the second part (430000) and subtract
