Answer:
#5
Area = Area of bigger triangle - Area of small triangle

#8
Area = area of square + area of two right angled triangles

Your answer would be 12x + 8 because there are 4 sides to a square and they are all 3x + 2, so you would need to multiply 3x + 2 by 4 which you can do by expanding brackets which gives you 4(3x + 2) and thus when you multiply it out you get 12x + 8. I hope this helps!
