The difference between 342 and 324 is different because the digits 2 and 4 are flipped.
342 and 324 are alike because they have the same amount of digits. hope that helped.
3) Vertex: (-7, 0) Axis of Symmetry: x=-7
6) Vertex: (-2, -1) Axis of Symmetry: x=-2
First we expand the brackets:
-2a + 8 + 6a = 36
4a + 8 = 36
We then need to get the a's onto one side and the numbers onto the other:
4a = 28
We can then divide to get an x by itself:
a = 28/4 = 7
The answer is the hypotenuse has a length of 5.
