Answer:
its12
Step-by-step explanation:
Let x represent the missing sides measurement.
x+x+28=52
combine like terms
2x + 28 = 52
subtract 28 from both sides
- 28 - 28
2x = 24
divide both sides by 2
x = 12
plug it back in
one leg is 12 inches
the other leg is 40 inches
x^2+ 2x +-48
product: -48 sum: 2
8, -6
x^2 +8x - 6x - 48
=> x(x+8) -6(x+8)
=> (x+8)(x-6)
