Foil the binomials
First: n*n=n^2
Outer: n*-5=-5n
Inner: -3*n=-3n
Last: -3*-5=15
Put it together and simplify
n^2-5n-3n+15
n^2-8n+15
Final answer: A
98 - x² = 0
x² = 98
x = ±√98
Lets factor 98
98 | 2
49 | 7
7 | 7
1
So, 98 = 2 . 7 . 7 = 2 . 7²
x = ±√2.7²
x = ±7√2
First you must find the rate of both taxes. Since its 8% and 6%, you must add them both together, then divide them by 100.
14/100 = .14
Then for both rates you must add 1 because it is a tax increase.
1 + .14 = 1.14
Finally times 37.50 with 1.14
37.50(1.14) = <span>42.75

<span>$42.75 is the answer.</span>
3,5 is the answer i belive
