The was to solve this problem is to get the letter, in this problem z by itself. so you would move 14.5 to the other side of the equal sign by subtracting. so the answer would be a = -9.1
First brake the figure into 3 rectangles . One across and 2 going up and down . Then solve for the small figures and add up all the areas together . Hope this helps .
12 - 3 = x , 9 = x . hope this helps
The greatest common factor of the number 6 is 1
From the figure, the vertices of the given triangle are
(-3,4), (1,3) and (5,5).
The given transformation is (x,y) -> (x+3, y-2).
Therefore the coordinates of the transformed triangle are
(-3+3,4-2), (1+3,3-2), (5+3,5-2) = (0,2), (4,1), (8,3)
The transformed triangle is shown in red color.
