Answer: 10.7x + 5
Step-by-step explanation:
(3.5 + 7.2)x + (-5 + 10) = 10.7x + 5
Answer:
Cube
Step-by-step explanation:
The cubed root of 8 = 2 because 2³ = 8.
So 8 is perfect cube.
Answer:
angle Lmp=77degrees and angle nmp = 103degrees
<u>Answer:</u>
3/5
<u>Step-by-step explanation:</u>
We are to find the similarity ratio of a cube with volume 
to a cube with volume 
.
We know the formula for the ratio of two cubes:
where 
is the similarity ratio of the two cubes.
Substituting the given values in the formula to find :
Therefore, the similarity ratio of the two cubes is 3/5.
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
