Hey there,
Let's say that the first piece is x cm
1st = x
2nd = x + 25%
3rd = x - 25%
100% = 240 cm
1% = 240 / 100
= 2.4cm
x + x + 25 + x - 25 = 100
3x + 25 - 25 = 100
3x = 100 - 25 + 25
3x = 100
3x = 240 cm
x = 240 / 3
= 80 cm
1st piece = 80 cm
2nd piece = 80 + (25% x 80)
= 80 + 20
= 100cm
3rd piece = 80 cm - (25% x 80)
= 80 cm - 20
= 60cm
Hope this helps :))

Answer:
The daily cost of cooling the large warehouse with the same model of air conditioner is 
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its volumes is equal to the scale factor elevated to the cube
In this problem
The scale factor is equal to 2.5
so
The scale factor elevated to the cube is 
To estimate the daily cost of cooling the large warehouse with the same model of air conditioner, multiply $125.00 by the scale factor elevated to the cube
so

The answer is B: (x-1)(x-6)(x+6)
