Weather I think I'm not sure
Answer:
Step-by-step explanation: We have been given 4 expressions. We are asked to choose the expression that represents sum of cubes.
We know that sum of cubes is in form .
We can see that 1st and 2nd option has a negative sign. Therefore, these options cannot be sum of cubes.
Let us check 3rd and 4th options one by one.
We can rewrite our expression by writing terms as cubes:
Therefore, expression is a sum of cubes.
In 4th expression, we can see that . We cannot represent it as a cube. Similarly, we cannot represent as a cube. Therefore, 4th expression is not correct.

Answer:
Step-by-step explanation:
you need to find the distance between points L, M, N to know the length of sides LM, MN, NL
use the distance formula
d= √(x2-x1)² +(y2-y1)², where the points are (x1, y1) and (x2, y2)
LM = √(4-1)² + (-3- -3)² = √3² + 0² = 3
MN = √(1-1)² + (-3-0)² = √0² + 9 = 3
NL = √(4-1)² + (-3-0)² = √3² + 9 = √18 = 3√2
The perimeter is LM+MN+NL = 3+3+3√2 = 6+3√2 ≈ 10.243
