Step-by-step explanation:
The area, A, in square yards, of a rectangular garden, is given by the function.

We know that, the area of the rectangle is given by :

Where l is length and b is breadth

Length = 2x
Breadth = (15-x)
For zeoes,

Length = 15 yards
Breadth = (15-15) = 0 yards
Hence, this is the required solution.

Answer:

Step-by-step explanation:
Since interest is compounded semi-annually (half a year or 6 months), in a spawn of 2 years, the interest will have been compounded 4 times. As given in the problem, each time the interest is compounded, the new balance will be 107% or 1.07 times the amount of the old balance.
Therefore, we can set up the following equation to find the new balance after 2 years:

15000 because 15kg x 1000 = 15000g
5x-9 = 3x+3
2x-9 = 3
2x = 12
x= 6
plz mark branliest, hopoe this helps :)
