Ashop sells matching hats and scarves. the scarves cost 1.5 times as much as the hats. write two patterns that could represent the costs of 1, 2, 3, 4 and 5 hats and scarves. list the first 5 terms of each pattern. then explain how to find the cost of 6 hats and scarves, using the patterns you wrote.

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.

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
