4times x with an exponent of 2 plus 2 times y with an exponent of 4. x=-3 y=2
i already know the answer is 68 but can someone explain how that’s the answer ?

Step-by-step explanation:

Your equation is:

You also know that x = -3 and y = 2. You can rewrite the equation by substituting x and y with their actual values:

First, you want to do the exponentiation (meaning you want to calculate and parts). equals 9 and equals 16.

So the equation now is:

Now you want to do multiplication. equals 36 and equals 32. So you're left with:

Which equals 68.

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
