If the neighbor was 10 and Victoria was 14, then then sum of their ages would be 24. So actually it would be (v + 4) + x = 14 and which would mean Victoria would have to be 9 and her neighbor is 5. There. I think that's right
The perimeter is the measure around the shape, so just add all the sides together- 6+5x+x+2 6x+8 Since this is a right triangle, you multiply the legs (6 and x+2) and divide by 2 6(x+2) 6x+12 /2 3x+6
