Answer:
$378
Step-by-step explanation:
Full price: 1.00($450) = $450
20% off: 0.20($450) = $90
Sale price (after 20% off): (1.00 - 0.20)($450) = 0.80($450) = $360
Final price, including tax: (1.00 + 0.05)($360) = $378
the first 9 is just the number 9 in the ones place, and the 9 next to the 2 is in the tens place so its value is 90

n= -4, 3
Step-by-step explain
n^2 + n = 12
n^2 + n - 12 = 0
n^2 + 4n - 3n - 12 = 0
n(n+4) -3(n+4) = 0
(n-3) (n+4) = 0
n-3 = 0 = n=3
n+4 = 0 = n=-4
