Stacia needs 39 diamonds for every 3 chandeliers she makes. how many diamonds would stacia need to make 4 chandeliers and 10 chandeliers?

Well, since we know that 39 diamonds are needed for 3 chandeliers, it would be helpful to know how many diamonds are needed for 1 chandelier. To find this, we can divide 39 by 3 to see she needs 13 diamonds for one chandelier. Now, all you need to do is multiply 13 by the number of chandeliers Stacia is making! 13 x 4 is 52, and 13 x 10 is 130. Therefore, if she wanted to make 4 chandeliers, she would need 52 diamonds. If she wanted to make 10 chandeliers, Stacia would need 130 diamonds.

 Hope I helped! <3

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1

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
