Question

. el perímetro es 18
X-3
X-2​

Answer 1

7. el perímetro es 18

2(x-3) + 2(x-2) = 18

2x - 6 + 2x - 4 = 18

4x = 18 + 10

x = 28/4

x = 7

remplazando

x - 3 ---- 7 - 3 = 4

x - 2 ---- 7 - 2 = 5

8. el perímetro es 38

2(x-3) 2(x+2) = 38

2x -6 2x +4= 38

4x -2 = 38

4x = 40

x = 10

remplazando

x-3 ----- 10 - 3 = 7

x+2 ----- 10 + 2 = 12
