A. they sold the least lemonade with the recipe that used 3 lemons
b. they sold the least lemonade with the recipe that used 7 lemons
c. they sold the most lemonade with the recipe that used 3 lemons
d. they sold the most lemonade with the recipe that used 7 lemons

B. They sold the least lemonade with the recipe that used 7 lemons

Step-by-step explanation:

B. They sold the least lemonade with the recipe that used 7 lemons

Step-by-step explanation:

As can be seen from the graph the points are

(3, 37)

This means that when they used 3 lemons then they sold around 37 cups

(4, 32)

This means that when they used 4 lemons then they sold around 32 cups

(5, 40)

This means that when they used 5 lemons then they sold around 40 cups

(6, 35)

This means that when they used 6 lemons then they sold around 40 cups

(7, 26)

This means that when they used 7 lemons then they sold around 26 cups

It can be seen that the last case is when they sold the least number of cups.

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
