Answer:
18
Step-by-step explanation:
A rectangular prism has four parallel edges along its length, four parallel edges along its width, and four parallel edges along its height.
We want to know how many different pairs of parallel edges there are. Starting with the length, the number of unique pairs is:
₄C₂ = 6
The same is true for the width and height. So the total number of different pairs of parallel edges is:
3 × 6 = 18
Answer:
24p - 35
Step-by-step explanation:
Step 1: Distribute.
Step 2: Combine like terms.
Therefore, the answer is 24p - 35! I hope this helped you.
I rounded it to about 0.040... I havent done this in a while tho so
Let the width be x.
width = x
length = x + 8
The area is 20 ft²
x(x + 8) = 20
x² + 8x = 20
x² + 8x - 20 = 0
(x + 10) (x - 2) = 0
x = -10 (rejected) or x = 2
Width = x = 2 ft
Length = x + 8 = 2 + 8 = 10 ft
Answer: The width is 2 ft and the length is 10ft.
