<span>We have to find the product : ( 9 t - 4 ) ( - 9 t - 4 ) = - ( 9 t - 4 ) ( 9 t + 4 ) After that we can use the difference of squares. The formula is: ( a + b ) ( a - b ) = a^2 - b^2. In this case: - ( 9 t - 4 ) ( 9 t + 4 ) = - ( 81 t^2 - 16 ) = - 81 t^2 + 16 . Answer: B ) - 81 t^2 + 16.</span>
Answer: 45ft.
Step-by-step explanation:
Let assigned the value of x to the unknown lenght.
Therefore, the Length = xft
The with is 1/3 of the length and this. = 15ft.
Now , to get the length, we equate both together and then solve for x .
1/3 of x = 15
x/3 = 15
To get x, we multiply both side by 3
x = 45ft
The of the pool = 45ft.
