Agardener has a rose garden that measures 30 feet by 20 feet. he wants to put a uniform border of pine bark around the outside of the garden. let x be the width of the border in feet. write an expression for the total area of the border in terms of the width x.

4x² +100x

Step-by-step explanation:

The total area of the garden plus the pine bark border is given by:

The area of the garden alone, without the border, is:

Subtracting the total area by the area of the garden gives us the area of the border:

The total area of the border is described by 4x² +100x.

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
