Answer:
687
Step-by-step explanation:
By seeing the picture below
you can divide the shape into 3 rectangles and add those three areas to find total area.
A = 23 * 11 + 22 * 14 + 7 * 18
= 253 + 308 + 126
= 687
15a =6a - 90
Move all the numbers with variables to one side
15a - (6a) = 6a -(6a) -90
9a = -90
9a/9 = -90/9
a = -9
Hope this helps
