3 x - 3 ≥ 12 need answer pls

Step-by-step explanation:

First, you have to add 3 on both sides, because of reverse operation. The opposite of -3 is +3, so when you add 3 on both sides, the 3 on the left cancels out and the 12 because 12+3, which is 15. Now, the inequality should look like this: 3x > 15. Divide 3 on both sides so that only x remains. 3x/3= x, and 15/3= 5. So, x > 5, and it would be B. Since it just greater than and not greater than or equal to, it would be a open circle. Hope this helped :)

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
