Paper he needs = total surface area
So to break it down into 2D shapes, that prism has 2 2D triangles, and 3 2D rectangles of different sizes.
The triangles are the same size, since you have 2, just multiply 2 by the formula for the area of a triangle: 1/2(base)(height) which is 2x1/2(5)(12) = 60
Next you'll need the area of all the rectangles: length x width. which would be (5 x 5) + (13 x 5) + (12 x 5) = 150
So the total amount of wrapping paper he'd need is 150mi^2
Answer:
−13x+18
Step-by-step explanation:
=−4x+(−9)(x)+(−9)(−2)
=−4x+−9x+18
Combine Like Terms:
=−4x+−9x+18
=(−4x+−9x)+(18)
=−13x+18
The width of rectangle is
cm and length is
cm.
Step-by-step explanation:
Let,
Width of rectangle = w
Length of rectangle = 
Perimeter of rectangle =
cm
Perimeter = 2(Length + Width)

Dividing both sides by 4

Width of rectangle = 

The width of rectangle is
cm and length is
cm.

Answer:
1. Given
2. Distributive property
4. Division property
Step-by-step explanation:
Answer:
x>-4.5
Step-by-step explanation:
- 11x + 32.5 < 82
Subtract 32.5 from each side
- 11x + 32.5-32.5 < 82-32.5
- 11x < 49.5
Divide each side by -11. remembering to flip the inequality since we are dividing by a negative
-11x/-11 > 49.5/-11
x>-4.5
