Answer:
A.
Step-by-step explanation:
The Elimination Method is the method for solving a pair of linear equations which reduces one equation to one that has only a single variable.
If the coefficients of one variable are opposites, you add the equations to eliminate a variable, and then solve.
If the coefficients are not opposites, then we multiply one or both equations by a number to create opposite coefficients, and then add the equations to eliminate a variable and solve.
When multiplying the equation by a coefficient, we multiply both sides of the equation (multiplying both sides of the equation by some nonzero number does not change the solution).
So, option B is not allowed (it is not allowed to multiply only one part of the equation)

Answer:
The last one
Step-by-step explanation:
A scalene triangle has no similarities between the angles or the sides
In the shown triangle none of the sides are similar and none of the angles are congruent therefore this is a scalene triangle
Reasons why its not the other answers
- This is not an acute triangle. In order for it to be an acute triangle all of the angles have to have a measure less than 90 degrees. There is an angle with a measure of 120 degrees the triangle is not an acute triangle
- This triangle is not an isosceles triangle. In order for it to be an isosceles triangles it has to have at least one congruent side. None of the sides are congruent therefore it is not an isosceles triangle
- This is not a right triangle. In order for it to be a right triangle one of the angles has to have a measure of 90 degrees. Because none of the angles measure 90 degrees it is not a right triangle
In conclusion the answer would be that this triangle is a scalene triangle
you first have to simfly in the partithies always then solve and prove done!
