In scientific notation, it would be 2x10^3.
An easy trick to help remember when it is a multiple of 10 is that you do the numbers that aren't zero (2) times 10 and the exponent is how ever many zeros there are after the other numbers (3).
Area of polygon = (number of sides × length of one side × apothem)/2
One solution to your problem is 15(1-2x)
We start qt 72 degrees,
3 1/5 = 16/5 = 3.2 x 10 minutes = 32 degrees.
72 + 32 = 104 degrees.
Cool Time:
4 2/7 = 30/7 = 4.28571429 x 7 minutes = 30 degrees.
104 - 30 = 74
So we went from 72 to 74 degrees, that is a 2 degree difference.
This is what i got, i hope i understood the question correctly.v
The augmented matrix is,

We have given system of linear equation is,

<h3>What is the meaning of augmented matrix?</h3>
In an augmented matrix, each row represents one equation in the system and each column represents coefficients (with signs) of variables or the constant terms.
So, the first row is

the second row is

and the third row is

Therefore the augmented matrix for this linear system is,
