When you divide these, factor both the numerator and the denominator to see if anything cancels out.  That's the best way to do it.  Easier than long division of polynomials, although it can also be done that way.  Factoring both the numerator and denominator gives you this:  \frac{(x-2)(2x+3)}{(x-2)(x+2)}.  The (x-2) factor cancels out in the top and bottom leaving you with just \frac{2x+3}{x+2}.  That's your answer.

Which expression is equivalent to 144^3/2?
ira [324]

we are given

(144)^{\frac{3}{2} }

we can write it as

144=12 \times 12

144=12^2

we can replace it as

(144)^{\frac{3}{2} }=(12^2)^{\frac{3}{2} }

(144)^{\frac{3}{2} }=(12)^{2*\frac{3}{2} }

(144)^{\frac{3}{2} }=(12)^{3 }

(144)^{\frac{3}{2} }=1728...............Answer

You have 10 fewer quarters than dimes and 5 fewer nickels than quarters. the total value of the coins is $4.75. Set up a system
Yanka [14]
So 
x- quarters
y - dimes
z- nickels

The system of equations would be
x+10=y
z+5=x
x+y+z= 4.75
