No, it is not a perfect cube. A perfect cube is a number that is obtained when you cube an integer. For example, 8 (cube of 2), 27 (cube of 3) and 64 (cube of 4). Since -3 cannot be obtained by cubing an integer, it is not a perfect cube.
This question is referred to two similar triangles.
One triangle has sides x and x - 2.
The other triangle has the respective sides x + x + 5 and x - 2 + x + 1
Then you can state a proportionality relation between the sides>
[x + x + 5] / x = [x - 2 + x + 1] / [x - 2]
=> [2x + 5] / x = [2x - 1] / [x - 2]
=> (2x + 5)(x - 2) = (2x - 1)x
=> 2x^2 - 4x + 5x - 10 = 2x^2 - x
=> x - 10 = - x
=> 2x = 10
=> x = 10 / 2
=> x = 5
Answer: x = 5

Answer:
100 joules/ second
Step-by-step explanation:
5,000/50 seconds = 100 joules/ second
Answer:
option 1
Step-by-step explanation:
cube root of 125 = 5
cube root of 27 = 3
5+3 = 8
now take x^10 =cube root of x^(3+3+3+1)
cube root of x^10 = x^(1+1+1)+*cube root of x
cube root of y^13 = cube root of y^(3+3+3+3+1)
= y^4*cube root of y
so answer is opt 1
