Answer:
I think its −1306800x+91040454
Step-by-step explanation:
Let's simplify step-by-step.
32+100(−3x+209)(662)+11+34
Distribute:
=32+−1306800x+91040400+11+34
=9+−1306800x+91040400+11+34
Combine Like Terms:
=9+−1306800x+91040400+11+34
=(−1306800x)+(9+91040400+11+34)
=−1306800x+91040454
if you notice the triangle on the left-hand-side, it has a base of 8 ft and a height/altitude of 10.
now, the triangular pyramid has 3 of those triangles standing up, and one at the base lying down, so 4 triangles with that base and altitude. So we can simply find the area of all 4 of those triangles, sum them up and that's the area of the triangular pyramid.
