A=LW
L=W-4
A=252
sub W-4 for L
A=(W-4)(W)
252=(W-4)(W)
252=W²-4W
minus 252 both sides
0=W²-4W-252
what 2 numbers multiply to get -252 and add to get -4
-18 and 14
0=(W-18)(W+14)
set to zero
W-18=0
W=18
W+14=0
W=-14
false, we can't have negative width
Width=18
L=W-4
L=18-4
L=14
length=14cm
width=18cm
Answer:
1) 2(t - 7)(t + 1)
2) $32,000
Step-by-step explanation:
v(t) = 2t² - 12t - 14
v(t) = 2(t² - 6t - 7) = 2(t - 7)(t + 1)
x = -b/2a = 6/2 = 3
y = 2(3)² - 12(3) - 14 = -32
(3, -32) means at 3 months, -32 thousand dollars
35% are in display cases which means 65% are on the wall.
this means 195 cars is 65% of the collection.
to get total number of cars in the collection divide 195 by 65%
195/0.65 = 300
answer: 300 total cars
