Easy find the least common product. In this case just take the values 1 through 5 and multiply each by 15 and 6 and the first equal product is your answer. In the end you should get 30 minutes.
Answer:
x = 5
Step-by-step explanation:
Given
8 = 
Multiply both sides by 3 to clear the fraction
24 = 5x - 1 ( add 1 to both sides )
25 = 5x ( divide both sides by 5 )
x = 5

Answer:
20 cm is the side of the bigger square.
Step-by-step explanation:
Let one square's side be x,
Then another squares side will be ( x + 5 )
- <em>Formula for square's area: side²</em>
Total area:
- x² + ( x + 5 )² = 625
- x² + x² + 10x + 25 = 625
- 2x² + 10 x + 25 - 625 = 0
- 2x² + 10x - 600 = 0
- 2(x² + 5x - 300) = 0
- x² + 5x - 300 = 0
- x² + 20x - 15x - 300 = 0
- x(x + 20) -15(x + 20) =0
- x = -20, 15
- x = 15
So one square's side is 15 cm
Then the bigger square has:
