1. 5x + 6 = 2 + 3x
-3x. - 3x
-------------------------
2x + 6 = 2
- 6. - 6
-------------------------
2x = -4
---- -----
2. 2

x = -2

2. 2(6 -2y) = -1(4y-9)
12 -4y = -4y + 9
+4y. +4y
----------------------------
.12 /=\ 9
No solution

3. 2z-6 = 2(z+2) + 10
2z -6 = 2z + 4 + 10
2z -6 = 2z +14

Answer:

a) p = 88\,cm, b) p = 24\,cm, c) p \approx 25.424\,m, d) p \approx 39.368\,cm

Step-by-step explanation:

a) The perimeter is the sum of the three sides of the internal square and the remaining sides of the external rectangle, that is:

p = 3\times 8\,cm + 2\times 4\,cm +2\times 20\,cm + 16\,cm

p = 88\,cm

b) The perimeter is the sum of the two sides of the internal triangle and the remaining sides of the external rectangle, that is:

p = 2\times 4\,cm + 2\times 6\,cm + 4\,cm

p = 24\,cm

c) The perimeter is the sum of the two sides of the circular section and the three sides of the lower rectangle, that is:

p = \frac{\pi}{2}\times 6\,cm + 8\,cm + 6\,cm + 2\,cm

p \approx 25.424\,m

d) The perimeter is the sum of the external sides of the triangle and rectangle, that is:

p = 10\,cm + 12\,cm + 12\,cm + 12\,cm - \sqrt{(12\,cm)^{2}-(10\,cm)^{2}}

p \approx 39.368\,cm
