Answer:

Length = 10cm

Width = 12cm

Step-by-step explanation:

let the width of the rectangle be x cm

then length of the rectangle =(x-2) cm

area of the rectangle= 120cm²

x(x-2)=120

x²-2x-120=0

x²-12x+10x-120=0

x(x-12)+10(x-12)=0

(x-12)(x+10)=0

x=12 or,x=-10

length can never be negative

therefore, x=12

length is 10cm

and width=12cm

Find the zeros, vertical asymptote, horizontal asymptote, slant asymptote, and graphing points.
sasho [114]
First, simplify fraction
(x+4)/((x-2)(x+3))
good
set numerator to zero
x+4=0
x=-4

VA
set denom to zero
(x-2)(x+3)=0
VA's at x=-3 and x=2

HA
for p(x)/q(x)
degreee of p(x)<q(x)
HA=0
no slant asymtote
does it cross HA?
0=(x+4)/(x^2+x-6)
0=x+4
-4=x
it crosses at (-4,0)

to graph
plot point (-4,0)
draw assymtotes
y=0
x=2
x=-3

go from top left to middle botttom to top right
reverse 'L' on top left going through (-4,0)
upside down 'U' at middle
'L' at right top
