26 because they’re are 26 heads..

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.

Move the decimal's place 7 times to the right. That means that 12.5*10^7 = 125*10^6. Now add 6 zeros: 125,000,000.
You can actually use a calculator to check your answers if it is allowed.
Answer:
-5cd
Step-by-step explanation:
<u>Simplifying:</u>
- -3cd - d(2c - 4) - 4d = ⇒ parenthesis
- -3cd - 2cd + 4d - 4d = ⇒ simplify like terms
- -5cd ⇒ answer
The first choice is correct one.
