we have

To find the zeros equate the function to zero

Group terms that contain the same variable, and move the constant to the opposite side of the equation

Factor the leading coefficient

Complete the square. Remember to balance the equation by adding the same constants to each side


Rewrite as perfect squares


square root both sides




therefore
the answer is
The zeros of the quadratic function are
and 
A = (P/4)(P/2 - P/4)
= (P/4)^2
Therefore it is a square
Playground
256 yd^2
P least perimeter
256 = (P/4)^2
P/4 = √256
= 16
P = 4*16
= 64
The least fencing is 64 yards.

Answer:
15.
Step-by-step explanation:
3.75 / 25 = 15.
Answer: $1,540
Step-by-step explanation:
Given the following amount charged by a worker :
First 45 hours = $14 per hour
time and half for the next 10 hours
Double time for all hours after that:
If he worked for 80 hours :
First 45 hours = (45 × $14) = $630
Next 10 hours:
Time and half for 10 hours is equivalent to (10 × 1.5) = 15 hours
(15 × $14) = $210
Double time for all subsequent hours :
80 - (45 + 10) = 80 - 55 = 25
Double time : (2 × 25) = 50 hours
(50 × 14) = $700
Hence, total amount earned :
($630 + $210 + $700)
= $1,540
