3x+9x=6x+42 add simalar elements 3x+9x=12x
12x=6x+42
12x-6x=6x+42-6x subract 6x from both sides
6x=42 simplify
6x/6=42/6 divide both by 6
x=7
Hmm this ones tricky.....
For finding surface area we add all the surface of the prism- 60×2=120(because in the prism there are two triangle so we are multiplying the area of triangle with 2) know we will multiply 40×8=320 perimeter is the sum of all sides. surface area= 320+120=440
