Answer:
<u>36 in²</u>
Step-by-step explanation:
<u>Area of the figure</u>
- Area (small rectangle) left + Area (big rectangle) right
- 3 x (6 - 4) + 5 x 6
- 3 x 2 + 30
- 6 + 30
- <u>36 in²</u>
----------------------------------
Define x :
----------------------------------
Let the width be x.
Width = x
Length = 2x + 5 // Length is 5ft longer than twice the width
----------------------------------
Formula for Perimeter :
----------------------------------
Perimeter = 2 (Length + Width)
----------------------------------
Find Width :
----------------------------------
58 = 2 ( 2x + 5 + x) // Substitute Length and Width into formula
58 = 2 (3x + 5) // Combine like terms
58 = 6x + 10 // Apply distributive property
48 = 6x // Take away 10 from both sides
6x = 48 // Switch sides. Make x the subject
x = 8 // Divide by 6 on both sides
----------------------------------
Find Length and Width :
----------------------------------
Width = x = 8 ft
Length = 2x + 5 = 2(8) + 5 = 21 ft
--------------------------------------------------------------------
Answer: The length is 21 ft and the width is 8 ft.

Answer:
I have a formula for differentiating a questions on differentiation
Step-by-step explanation:
I have not published it yet but can give a brief summary of it will later use it to solve questions here after publishing it
any time you a given a function or a question to differentiate always write it in this form y=am...will explain the rest later after publishing it. it works for all kind of differentiation questions like product or quotient type of questions
Answer:
12x6+2(6-1)
72+2x5
72+10
82
82 is the answer.
Step-by-step explanation:
Just replace the X's in the problem with 6.
