Factor the numerator and denominator of the first fraction...
(n^2-6n-4n+24)/(n^2-6n-7n+42)
(n(n-6)-4(n-6))/(n(n-6)-7(n-6))
((n-4)(n-6))/((n-7)(n-6)), note that the (n-6)s cancel out leaving:
(n-4)/(n-7) so now the equation looks like:
(n-4)/(n-7)-9/(n-7) since they now have a common denominator...
(n-4-9)/(n-7) which is
(n-13)/(n-7)
The dress pants cost 40 bucks....the coupon for the dress pants is y percent off the dress pants...
so the part of the expression that represents the percent that skylar will pay for the dress pants is : (1-y)40
Remember that an exponent means repeated multiplication.
The exponent of 4 means you have four 's mutiplied together:
And then each exponent of 2 inside means you have two 's multiplied inside each set of parentheses.:
There are 8 b's there when you expand this out.
