6z - 12 + 4 = 10
6z -8 = 10
6z = 18
z = 3
Divide the polygon into separate shapes. Like a rectangle and then a triangle.
find the areas of those shapes and then add them together.
13y-2b=15y
2b=2y
2b=2y
2b=2y
Answer: you can only add like terms, for example; 2x + 3x = 5x as they both have an x next to the numbers.
you cannot simplify 2 + 4x as they both don’t have an x next to them.
hence why, the answer to 2x^2 + 15x^2 would be 17x^2
