Answer:
3x^2 - 9x + 8
Step-by-step explanation:
To simplify:
- Distribute the -1 into the second term.
- Collect and combine like-terms (terms with the same variables or powers)
The expression can be rewritten has (2x^2 - 5x + 3) -1(-x^2 + 4x - 5)
After distributing the -1, the equation becomes:
- (2x^2 - 5x + 3) + (x^2 - 4x + 5)
The like-terms are:
- 2x^2 and x^2
- -5x and -4x
- 3 and 5
Combine the like-terms:
- 2x^2 + x^2 = 3x^2
- -5x - 4x = -9x
- 3 + 5 = 8
Substitute the simplified like-terms into the expression, in descending order:

To find the surface area of the given figure identify all the faces on the figure, calculate the area of each face and then sum the areas:
Measures in red
Number of faces in green, total faces 9
Area of a triangle:

Area of a rectangle:

Area of faces 1 and 2(rectangles):

Area of faces 3 and 4 (triangles):

Area of faces 5 and 6 (rectangles):

Area of faces 7 and 8 (rectangles):

Are of face 9 (rectangle):

Total surface area:

<h2>Then, the surface area of the given figure is 1108 square inches</h2>
