Given a quadratic equation

1. the first thing we do when we want to compete the square, is write the coefficient of x as 2 times a number.
In our case the coefficient of x is 10, so we write 10 as 2*5
2. then we write +

and -

to the expression:



Answer:
Answer:
314 ft²
Step-by-step explanation:
Data provided in the question:
Depth (height) of the pool =
of its radius
let the radius be 'r' ft
thus,
Depth (height) of the pool, h =
ft
Volume of the pool = 1570 ft³
also,
Volume of cylinder = πr²h
thus,
1570 ft³ = πr²h
or
1570 ft³ = 
or
3140 = 3.14 × r³ [ π = 3.14 ]
or
r³ = 1000 ft³
or
r = 10 ft
Thus,
Area of the bottom surface = πr²
= 3.14 × 10²
= 314 ft²
Answer:

Step-by-step explanation:
Formula for finding the volume of a triangular prism is given as:

where,
b = breadth = 7cm
h = height = 6cm
l = length = 10cm
Thus,




She needs 15 crates of limes
2x6=12
40x6=240 limes required to make 12 liters
240/16=15 crates needed
