The new dimensions will be 8 which is (4) and 12 which is (6) so the area is 96 feet squared.
Answer:
= (a + <u>4</u>) (a - <u>4</u>)
Step-by-step explanation:
The given equation is 
Now, By ALGEBRAIC IDENTITY:

Here, taking
, we get b = 4
as 
So, the right hand side of
is (a + 4) (a-4)
The answers are:

Have a good day! (or night, depending when u see this)
It depends on how it's used.
For example if it's angles it could be because of Vertical Angles.
If it's Triangles it could be Definition of Congruent Triangles.
Answer:
Step-by-step explanation:
Given
speed of cyclist A is 
speed of cyclist B is 
At noon cyclist B is 9 mi away
after noon Cyclist B will travel a distance of 6 t and cyclist A travel 4 t miles in t hr
Now distance of cyclist B from intersection is 9-6t
Distance of cyclist A from intersection is 4 t
let distance between them be z

Differentiate z w.r.t time



Put 
therefore
