(x - 3)^{5}
(x - 3)(x - 3)(x - 3)(x - 3)(x - 3)
(x^{2} - 6x + 9)(x^{2} - 6x + 9)(x^{2} - 6x + 9)(x - 3) \\(x^{4} - 12x^{3} + 54x^{2}  - 108x + 81)(x - 3) \\x^{5} - 15x^{4}  + 90x^{3} - 270x^{2} + 189x - 324

15 feet of edging costs $24.98. How much will 28 yards cost?
GuDViN [60]

Answer:

  139.888 $

Step-by-step explanation:

Data :

28 yd / 5yd = 5.6

    5.6 × 24.98 =  139.888

Find ten rational numbers between -1 by 5 and 1 by 2 ​
uysha [10]

Answer:

Step-by-step explanation:

First both the rational numbers should have same denominators. So, find least common denominator

Least common denominator is 10

\frac{-1}{5}=\frac{-1*2}{5*2}=\frac{-2}{10}\\\\\\\frac{1}{2}=\frac{1*5}{2*5}=\frac{5}{10}\\\\\\

Now multiply  the numerator  and denominators of the both the numbers by 10.

\frac{-2*10}{10*10}= \frac{-20}{100} \ and \ \frac{5*10}{10*10}=\frac{50}{100}\\\\\\Now\ 10 \ rational  \ numbers \ between\frac{-20}{10} \ and \ \frac{50}{100} \ is \\\\\\\frac{-19}{100},\frac{-18}{100},\frac{-17}{100},\frac{-16}{100}.\frac{-15}{100},\frac{-14}{100},\frac{-13}{100},\frac{-12}{100},\frac{-11}{100};\frac{-10}{100}

Which method is best using this equation 4x-2y=-2,-5x+6y=-15 and why
kipiarov [429]
I think that using the elimination method is the best, because it is the only method that I use when solving these types of equation. For example, for these two equations, you need to multiply one of the equations by a certain number so that you'd be able to find x and y. The elimination method is the method that tells you to do that. It is also the easiest method.

~Hope I helped!~
