Answer:
-1+√6
-1-√6
Step-by-step explanation:
x²+2x-5=0
x=(-2±√(2²-4(-5)))/2=(-2±√(4+20))/2=(-2±√24)/2
x₁=(-2+√24)/2 or x₂=(-2-√24)/2
x₁=(-2+2√6)/2 or (-2-2√6)/2
x₁=-1+√6 or x₂=-1-√6
original quantity : 10 for $1
new quantity: 4 for $1
now we have to find each percent change
10-4=6
6÷100=0.06
0.06=6%
the quantity went down 6%

Answer:
$17.97
Step-by-step explanation:
It should be no surprise that the total cost is the sum of the costs of the items being purchased.
We can add the costs of repeated items into the sum several times, or we can use multiplication to find their cost. Most folks use multiplication to find the sum of repeated numbers.
milk + strawberries + bananas
= $3.49 + 2×$4.99 +6×$0.75
= $3.49 +9.98 +4.50
= $17.97
