here is your answer
Step-by-step explanation:
option d.)5³/3³
The order of a matrix is m×n where m is the number of rows and n is the number of columns.
can you count and find what are m and n here?
Call the production cost 'C', the revenue 'R' and the number of CDs 'n':
C=2000+5n
R=10n
By definition Profit P = R-C, therefore P=10n-2000+5n = 5n-2000.
Answer:
A. 12 centimeters B. 4 centimeters C. 20 centimeters
Step-by-step explanation:
To find area you need to do the Height time the Length.
For A it is 3x4
For B it is 4x1
And for C it is 4x5
You get this equation by multiplying the amount of squares that the Height and Length measured!
Hope this helped!

Step-by-step explanation:
factor 4 out of the variable terms, as this helps.
but my approach is simply to define the target and then calculate "backwards".
we want to find
(ax + b)² = a²x² + 2abx + b²
and now we compare with the original equation :
a²x² = 4x²
a² = 4
a = 2
2abx = 16x
2×2×bx = 16x
4b = 16
b = 4
b² = 16, but we have only 3, so we need to subtract 16-3 = 13 from the completed square.
so, our equation is
(2x + 4)² - 13 = 0
(2x + 4)² = 13
2x + 4 = sqrt(13)
2x = sqrt(13) - 4
x = sqrt(13)/2 - 2
