Arectangular flower bed is enlarged so that its area increases by 14 m². the enlarged flower bed is a rectangle and its area is x2+9x+14 m².
what expressions represent the dimensions of the flower bed before the increase?
enter your answers in the boxes.
[ ] m and [ ] m

Dimensions of the flower bed before the increase are x meters  and x+9 meters.

Step-by-step explanation:

Since we have given that

A rectangular flower bed is enlarged so, its area increases by 14 m².

So, Enlarged area of flower bed =

We need to find the dimensions of the flower bed before the increase.

so, Let the original area be 'A'

so, it can be written as :

Since we know the area of rectangular flower bed is Length × Breadth

So, Dimensions of the flower bed before the increase are x meters  and x+9 meters.

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.
