Richard wants to make a garden with a perimeter of 16 feet, and length of 4 feet. He solves for the width by subtracting 8 from

Ostrovityanka [42]

The equation that can be used to solve this is:

$P =2W+2L\\OR\\P-2L = 2W\\\frac{P-2L}{2} = W$

Further explanation:

Let

$P\ be\ the\ perimeter\\L\ be\ the\ width\\W\ be\ the\ width$

The equation for the perimeter will be:

$P =2W+2L$

Given

P = 16 feet

L = 4 feet

W = ?

Putting the values in the perimeter formula

$16=2(4)+2W\\16=8+2W\\16-8= 2L\\8=2L\\L=\frac{8}{2}\\L=4\ feet$

The equation that can be used to solve this is:

$P =2W+2L\\OR\\P-2L = 2W\\\frac{P-2L}{2} = W$

Find the intervals on which f(x)=2xx2+64 increases.

Shtirlitz [24]

f(0)=64, f(1)=66, f(2)=72, f(3)=82, f(4)=96,...=2,6,10,14,...=2{1,3,5,7,...}
This can be written 2{2x+1}, so the intervals on which f(x) increases are 4x+2.

We can't tell what the question is here, but it looks like you want to know about the definition of domain and range.

The set of x-values is the domain.

The set of y-values is the range.

"range" is not another name for the set of x-values.
