Answer:
2340 mm
Step-by-step explanation:
We know that since the rectangular prism has a square base, the length and width are equal
So we have V = 10 * 10 * 15
For the small rectangular slab we can subtract 10 from 40 to get 30 for the length
Thus we have V = 30 * 4 * 7
Hope this helps
Answer:
19a+27b-54
Step-by-step explanation:
First distribute 7 into the first equation. (4a+3b-6) Multiply each coefficient and the constant by 7.
28a+21b-42
Then do the same for -3 and (3a-2b+4).
-9a+6b-12
Rewrite the equation 28a+21b-42-9a+6b-12.
Combine like terms: 19a+27b-54
Problem:
The area of the patio of a relative's house is 20 square meters.
The width of the patio is 2 meters.
What is the length of the patio?
Solution:
The area is:
A = (w) * (l)
Where,
w: width
l: long
Clearing l we have:
l = A / w
Substituting values:
l = 20/2
l = 10 meters
