Answer:
x=7
Step-by-step explanation:
first, subtract 3 on both sides:
3x=21
simplify by dividing 3 on both sides:
x=7
(a+b)^3 = a^3+b^3+3ab(a+b)
(a+b)^3 = (-1)^3
In the context of rubiks cube solving the rate at which one can solve a rubiks cube is determined by the number of cubes solved and the time taken
In this question we were told that moira solved a rubiks cube in 3 minutes 30 seconds
Let us convert time total time to seconds
3 minutes 30 in seconds = 3*60+ 30 = 180+30 = 210 seconds
Hence Moira rate = 1 rubiks cube/210 seconds
