Answer:

Step-by-step explanation:
Step one:
given data
3,700 mile
In scienctific notation or in standard form 3,700 mile is expressed as

The rate of change for function A is 2. It would originally be 2 over one but you can just simplify it down to 2. The rate of change for function B is 3. Which would also originally be 3 over 1.
Y = mx + c
y = 0.5x
y = 0.5*4 = 2
(4,2)
This is just combining like terms.....
6n2 - 5n2 + 7n2
n2 + 7n2
=8n2
Answer:
Width = 12 in
Length = 16 in
Step-by-step explanation:
Let, the Width of the rectangle = w in
Now, the length of the rectangle = (w + 4) in
Now, Perimeter = 56 in
Also, we know that
Perimeter of the Rectangle = 2 (Length +Width)
or, 2 (Length +Width) = 56
⇒ 2(w + 4 +w) = 56
or, 4w =56 -8
width = 12 in
So, Length = w + 4 = 12 + 4 = 16 in
