Answer:
width = 5k^2
length( 3k^2 +7k +4)
Step-by-step explanation:
15k^4 +35k^3 +20k^2
The width is the greatest common factor
We can factor 5k^2 out
5k^2( 3k^2 +7k +4)
The length is what is inside the parentheses

Step-by-step explanation: The answer of 1400 is correct.
What I did is I found the area of the figure assuming it was a rectangle, then I subtracted the corners that were removed.
1800 - 150 - 100 - 150 = 1400
Answer: the cost of 1 one-inch binder is $4
the cost of 1 three-inch binder is $7
Step-by-step explanation:
Let x represent the cost of 1 one-inch binder.
Let x represent the cost of 1 three-inch binder.
Jesse selected 3 one-inch binders and 3 two-inch binders, which cost a total of $33. This means that
3x + 3y = 33 - - - - - - - - - - 1
Luann selected 2 one-inch binders and 1 two-inch binder, which cost a total of $15. This means that
2x + y = 15 - - - - - - - - - - - 2
Multiplying equation 1 by 2 and equation 2 by 3, it becomes
6x + 6y = 66
6x + 3y = 45
Subtracting, it becomes
3y = 21
y = 21/3 = 7
Substituting y = 7 into equation 2, it becomes
2x + 7 = 15
2x = 15 - 7 = 8
x = 8/2 = 4
