Answer:
get 1 … what? free? half-price? something else?
Let x= price of 1 item
Then 3x= price of 3 items
Buy 2 , get 1 free
Total cost =2x
Discount =3x−2x=x
Discount percentage =x/(3x)=0.333…=3313%
Buy 2 , get 1 half price
Total cost =2x+0.5x=2.5x
Discount =3x−2.5x=0.5x
Discount percentage =0.5x/(3x)=0.1666…=1623%
9.055
Step-by-step explanation:
distance
= √(x₁ - x₂)² + (y₁ - y₂)
= √[7 - (-2)]² + [-5 - (-4)]²
= √[9]² + [-1]²
= √(81 + 1)
= √82
≈ 9.055
Hm let's see the answer should be by the definition of isosceles triangle
The square root of 325 is 18.03
