I attached the answer and explanation below
Answer:
- 8x = - 32
Step-by-step explanation:
Given
1 + 2x + 1 = 10, that is
2 + 2x = 10 ( subtract 2 from both sides )
2x = 8 ( divide both sides by 2 )
x = 4
Then
- 8x = - 8 × 4 = - 32
First convert the dimensions of the pyramid from feet to yards.
1 yard = 3 feet.
756 feet / 3 ft per yard = 252 yards.
480 feet / 3 ft per yard = 160 yards.
The formula for volume of a pyramid is: Area of the base x the height divided by 3.
Volume = 252 yds^2 x 160/3 = 63504 x 160/3 = 3,386,880 cubic yards.
Now to find the number of bricks needed. divide the total volume by the volume of 1 brick:
3,386,880 / 1.5 = 2,257,920 total bricks.
