The 4 treads require 4*10.25 = 41 inches, but you also require landings at each level, adding perhaps 72 inches. (Building codes vary.)
Somewhere between 41 and 113 inches of horizontal space will be required, perhaps more.
Answer:
<h2>m∠ABC = 72</h2>
Step-by-step explanation:
Answer:
1r + 8(400) = 3(r+400)
1r + 320 = 3r + 120
2r = 200
r = 200 / 2 = 1000
1400 * 3 = 420
100 + 320 = 420
Step-by-step explanation:
Perimeter of a rectangle = 6x + 8
Solution:
Given area of a rectangle =
Let us first factor the given polynomial.
Taking out common terms in the above expression
Taking out common term in the above expression
Area of a rectangle = l × b
Therefore, and
Perimeter of a rectangle = 2(l + b)
The answer is same if you take <em>l</em> = x + 3 and <em>b</em> = 2x + 1.
Hence, perimeter of a rectangle = 6x + 8.
