a spool holds 6.75 meters and a craft club buys 21 spools. what is the total cost if the ribbons costs 2 dollars per meter?
Burka [1]
● To do this, you need to multiply 6.75 by 21 to find out how many meters are in all. 6.75×21 is 141.75

● Next you multiply 141.75 by 2 to see how much it costs which is 283.5

● Since we're dealing with money, it would have two place values so we add a zero and we get $283.50

Subtract <br><br> \frac{3n+2}{n-4}-\frac{n-6}{n+4}
aalyn [17]
(3n+2)/(n-4) - (n-6)/(n+4)

common denominator (n-4)(n+4)

{(n+4)(3n+2)-(n-4)(n-6)}/{(n-4)(n+4)}

Use the foil method:

{(3n²+14n+8)-(n²-10n+24)}/{(n-4)(n+4)}

distribute negative sign:

{(3n²+14n+8-n²+10n-24)}/{(n-4)(n+4)}

subtract:

(2n²+24n-16)/{(n-4)(n+4)}

take out 2:

2{n²+12n-8}/{(n-4)(n+4)}
