Call the shorter piece 'x'.
The longer piece is (3x+1), you said so yourself.
They add up to 21 feet. (You said "together"; I have to assume that means "end-to-end".)
x + (3x + 1) = 21
x + 3x + 1 = 21
4x + 1 = 21
4x = 20
x = 5
3x + 1 = 16
The lengths of the pieces are 5-ft and 16-ft.
================================
Check:
Is (5 + 16) = 21 ?
Yes.
Is (16) = (3 x 5) + 1 ?
Yes.
Yay !

What is longer length or width?
The longer side is usually called "length".
Does the length of a pendulum effect how it swings?
Yes, the length of a pendulum affects its swing. The oscillation will be longer with a longer length and shorter with a shorter length.
What is an example of a rectangle?
A quadrilateral with two sides of the same length and then two sides of a longer same length :). It has four sides, two longer than the others. These four sides all come together at 90 degree angles. I hope this could help!
When put together two sticks are 142cm long one stick is 22cm longer than the other how long are the sticks i need someone to set this up as a equation?
Let the length of the short stick be s cm; then: The longer stick is s + 22 cm. And the two sticks together is: s cm + (s + 22) cm = 142 cm → 2s + 22 cm = 142 cm This can then be solved for s, the length of the shorter stick; from which the longer stick length can be found.
How does the length of the pendulum effect the pendulum?
The longer the length of the pendulum, the longer the time taken for the pendulum to complete 1 oscillation.
Why do you have short and long days?
The Earth's axis is on a tilt of 23.5 deg. This is what causes the days (daylight hours) to be longer in the summer and shorther in the winter.
What is longer length or width?

Word for having shorter than visible wavelength?
Longer than visiblie wavelength is Infrared. Shorther than visible wavelength is ultraviolet. Asking for answers here to the Guardian crossword is cheating. ;o)
Does the length of a pendulum effect how it swings?
Yes, the length of a pendulum affects its swing. The oscillation will be longer with a longer length and shorter with a shorter length.
How many hooks are generally needed to hold up a shower curtain?
So long as the curtain is up across a 1.5 metre bath (or a near to that length as makes no difference) then the number of hooks required is approximately 1 every 20 cm of curtain, which works out at somewhere between 10 and 14. The material of the curtain and its vertical length can also make a difference - longer drop leads to more hooks required (usually at a shorther interval apart).
What is an example of a rectangle?

What type of light has a longer wave length ultra violent or infrared?
Ultraviolet has the longer wave length Infrared has the lower wave length
When put together two sticks are 142cm long one stick is 22cm longer than the other how long are the sticks i need someone to set this up as a equation?
Let the length of the short stick be s cm; then: The longer stick is s + 22 cm. And the two sticks together is: s cm + (s + 22) cm = 142 cm → 2s + 22 cm = 142 cm This can then be solved for s, the length of the shorter stick; from which the longer stick length can be found.
How does the length of the pendulum effect the pendulum?
The longer the length of the pendulum, the longer the time taken for the pendulum to complete 1 oscillation.
What is the longer side the length or the width?
Conventionally, length is the bigger of the two.
Where is the length in the rectangle?
The length of a rectangle is typically considered to be the longer of the two sides, also referred to as the longer dimension. It is measured along the longer side of the rectangle from one end to the other.
How does length effect the period of a pendulum?
A longer pendulum has a longer period.
