Answer: Length = 42ft Width = 21ft
Step-by-step explanation:
Let "w" be width
W = 21ft
w x 2 = L
L = 42ft
Perimeter:
42+42+21+21
=126
Answer: 96 cm^3
To answer this, start by finding the volume of the square prism. The formula is L x W x H, therefore the volume is 3 x 3 x 10 = 90.
Then, find the volume of the pyramid on the top. Use the same formula but divide it by 3 because it is a pyramid. 3 x 3 x 2 / 3 = 6
Add 90 and 6 to get 96.
estimate by rounded to the nearest dollars
2 +1 +5 +2 +3 +9 +1 = $23
-2
23-2 = 21
yes the amount is reasonable

5x+17=-23
Subtract 17 on both sides
5x=-40
Divide by 5 on both sides
X=-8
Double Check:
5(-8)+17=-23
-40+17=-23
-23=-23
