What is the answer to A+4=14

You need to solve for A.

A + 4 = 14

Begin by doing the opposite of +4 on both sides of the equation. This means to subtract 4 from both sides of the equation

4 + 4 = 0 (do not include 0)

14 - 4 = 10

Now we have:

A = 10

So, 10 + 4 = 14.  This is true

1. The "triangle inequality" states that any of the sides of the triangle, is larger than the difference of the other 2 sides (the larger minus the smaller), and it is smaller than the sum of them.

2. So the third side of this triangle must be larger than 14-8=6 (in) and smaller than 14+8=22 (in)

3. So let a denote the remaining side, then   6 < a < 22, which means a can be any number in between 6 and 22 inches.
