Ab=9
How I got it
AC/CB = CE/CD. Or AC/3 = 16/4.
We can solve AC to be 12. To find AB, it is AC-3 which is 9.
So AB=9

Ok:
Step-by-step explanation:
So these triangles are similar. That means that the ration between their sides are the same. In this case, we have then:
AC/CB = CE/CD. Or AC/3 = 16/4.
We can solve AC to be 12. To find AB, it is AC-3 which is 9.
So AB=9

You will need 40 pounds of apples
This is how the whole equation goes:
1/x^-a = x^a
So, 1/5^-2 is the same as 5^2, which is 25.
