x=3.575

Step-by-step explanation:

-2x^3+8x^2-5x+7=0

Since we want to solve it graphically we can use a graphing calculator site like desmos or by using a Ti-89.

So a zero of a function is when it would hit the x-axis, so if we go onto desmos.com/calculator and type in our problem we can see that it hits the x axis at (3.575,0)

So our zero would be 3.575.

x=3.575

answer: the 4 kilogram bag

step-by-step explanation: this is because if you divide the number of kilograms into the total it will tell you how much each individual kilogram would be worth. 2 kilos is 7 and change 3 would be around 6 ish and the 4 kilo would be 4.6 and change and the 5 kilos would be like 4.88

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
