COMPLETING THE SQUARE (PROCESS):
Do a reverse factoring procedure to develop the following form of equation:
(t + a)^2 = b
where:
t = unknown variable
a = coefficient
b = coefficient
Then take square root of both sides to find value of unknown variable as follows:
t^2 + 10t = 75
(t^2 + 10t + 25) = 75 + 25
(t^2 + 5t + 5t + 25) = 100
(t + 5)(t + 5) = 100
(t + 5)^2 = 100
√(t + 5)^2 = √100
Two solutions exist:
+(t + 5) = 10
AND
-(t + 5) = 10
Thus:
t = 10 - 5 = 5
AND
t = -5 - 10 = -15
Answer:
t = 5
AND
t = -15
Answer:
5.99 per pair
Step-by-step explanation:
Take the cost of the package and divide by the number of pairs
29.95/5
5.99
Each pair costs 5.99

Work With Out A Calculator:
2.1 × 10 = 21
1.488 ÷ 2.1 = (1.488 × 10) ÷ (2.1 × 10)
14.88 ÷ 21 = 0.7085
0.7 Rounded
