Answer:
The perimeter of rectangle is 
Step-by-step explanation:
Let
x-----> the length of the rectangle
y----> the width of the rectangle
we know that
----> equation A
---> equation B (area of the constructed figure)
substitute the equation A in equation B

using a graphing tool -----> solve the quadratic equation
see the attached figure
The solution is

Find the value of x
----> 
Find the perimeter of rectangle


Thus, options A and D hold, from the simplifications above.
Let's consider the validity of the remaining options provided.




Hence, the correct options that apply are options A, D, E and F
Answer:

Step-by-step explanation:
Answer:
It is all determined by how many spaces and which way the decimal point moves.
Step-by-step explanation:
So here are two examples
<em>Example 1:</em>
500000.00
To write this in scientific notation you would move the decimal place to the left.
You would move it 5 digits to the left so the exponent of 10 would be 5

<em>Example 2</em>
0.0000042
Here to write this in scientific notation you move the decimal place to the right.
You would move it 6 digits to the right so the exponent would be -6
