Answer: 1.79 square meters</h3>
Work Shown:
A = area of the triangular front face
A = base*height/2
A = 0.8*0.1/2
A = 0.04
L = lateral surface area
L = combined area of all the rectangular faces
L = (perimeter of the triangular face)*(depth of the prism)
L = (0.1+0.8+0.81)*(1)
L = 1.71
SA = total surface area of the triangular prism
SA = 2*A+L
SA = 2*0.04+1.71
SA = 1.79 square meters

Answer:
-0.55n - 0.05
Step-by-step explanation:
You can start by distributing:
(0.25n - 0.3) - (0.8n - 0.25)
0.25n - 0.3 - 0.8n + 0.25
Then, you can combine like terms(0.25n & -0.8n; -0.3 & 0.25)
-0.55n - 0.05
