To solve 1-20, you plug in the number for the variable that the variable is equal to e.i. a) x = -3 so you plug -3 in every place there is an x
-2(-3)^2 - 3(-3) + 1
-2(9) +9 + 1
-18 +10
-8
The solution to a) is -8.

A=LW. 3.5*3.5=12.25 sq ft
Given:
Initial value = 25,000
depreciation = 15% per annum based on net book value
Net book value = 25,000 (1 - 0.15)^t
where t is the number of years
NBV = 25,000 (0.85)^5
NBV = 25,000 (0.4437)
NBV = 11,092.50
The approximate value of the car 5 years from date of purchase is 11,092.50
It is A. x = 2√3, y = 4√3
