Answer:
Don't know if you are still online but, I have an answer to 25. I got 5r-r^2-6
Step-by-step explanation:
I believe this equation is a polynomial equation where you combine like terms. When subtracting you distribute the negative first then combine the similar term, just like adding with an extra step involved. So you take 3r and 2r and combine them because (like mentioned), you combine the terms that are same. You add them and get 5r. Since -r^2 and six don't have the same terms, they stay the same and you combine the terms and make in it into a simplfied polynomial sequence. 5r-r^2-6.
Hope this helped! Sorry it took so long! Haven't done this since last year.
In order to estimate this problem we must first estimate the two numbers involved.
137,638 rounds up to 138,000.
Since the 6 is bigger than 5 it makes the number 7 round up to 8
Now..
52,091 rounds out to 52,000
Since the number to the left of the 2 is not bigger than 5 then it stays the same at 52,000
Now we have to add our estimated numbers.
138,000 + 52,000 = 190,000
Your answer is 190,000
Good Luck! :)

It could be 1,870. You multiply 70 by 25 which gives you 1,750, than you multiply 5 by 24 which gives you 120 and your answer will total out to 1,870
Width of the rectangle is 1 unit
Step-by-step explanation:
- Step 1: Let the length of the rectangle be x. Then the width = x - 5. Find dimensions of the rectangle if its area = 6 sq. units
Area of the rectangle = length × width
6 = x (x - 5)
6 = x² - 5x
x² - 5x - 6 = 0
x² - 6x + x - 6 = 0 (Using Product Sum rule to factorize)
x(x - 6) + 1(x - 6) = 0
(x - 6)(x + 1) = 0
x = -1, 6 (negative value is neglected)
x = 6 units
x - 5 = 1 unit
