Answer:
12960 is the answer happy to help
Step-by-step explanation:
The answer would be B because LWH=V, so taking the information given, L(19) times W(12) would equal 228 and 228 times the H would give us volume so B
Hope this helped ;)
Answer:
no solutions
Step-by-step explanation:
-4(5k-7) +2k= -2(9k+5)
Distribute
-20k +28 +2k = -18k -10
Combine like terms
-18k +28 = -18k -10
Add 18k to each side
-18k+18k +28 = -18k+18k -10
28 = -10
This is never true so there are no solutions
Answer:
Yes they are directly proportional quantities.
Step-by-step explanation:
We find the area of a square by;
A = length squared or (L)² , where 'L' stands for length and 'A' stands for area.
So Area = L²
Assume the length is a units and increase the length by 2 units
The initial area before increasing the length is a²
After increasing the length, the area becomes: (a + 2)² = a² + 4a + 4
Now we subtract the initial area from the final area and get;
(a² + 4a + 4) - a² = 4a + 4
So the new area increases by 4a + 4 units.
Hence, the area increases as the length increases implying that the area of a square is directly proportional to its length.
We denote this proportionality as;
A ∝ L
