Answer:
6 ft longer (total length of 15ft)
Step-by-step explanation:
the initial dimensions are:
length: 
width: 
the area area of the garden is given by:
so the original area is:
Since we need the area to be 
, and we can only change the length, the width will still be 8ft.
We substitute the value of the new area and the width to the equation for the area:
and we clear for the new length:
The length of the garden for the area to be , must be 15ft.
This means that if originally the length was 9 ft, now it has to be 6 ft longer.
Charge of Ralph:
Charge = $24 + $33 per hour
Let the time worked be = x.
For x hours, the cost = 33*x = 33x
Charge = 24 + 33x
24 + 33x = 189
33x = 189 - 24
33x = 165
x = 165/33
x = 5
The job took 5 hours.

Answer:
The other leg of the triangle is 12.
Step-by-step explanation:
Given:
Hypotenuse of triangle is 13 and a leg(Leg1) is 5.
Let, the other leg of the triangle (Leg2) be 
.
Now, putting the formula:
⇒ 
⇒
⇒
⇒
Taking square root both sides
⇒
⇒
.
Therefore, the other leg of the triangle is 12.
(5raise to power 5)÷(4)=3125/4)
