The area of the triangle is given by the functions area of triangle a: x2 + x area of triangle b: x2 - 3x which functions represents the sum of the areas of the two triangles? 1. 4x 2.-4x 3.x2-4x 4.2x2-2x

OPTION 4

Step-by-step explanation:

Let be f(x) the function that represents the area of Triangle A:

Let be g(x) the function that represents the area of Triangle B:

Then, you need to add the area of Triangle A and the area of Triangle B in order to find the sum of the areas (Let be h(x) the function that represents the sum of the the areas of triangles A and B):

Therefore, this is:

You can notice that this matches with the option 4.
