Suppose that the height (in centimeters) of a candle is a linear function of the amount of time (in hours) it has been burning.
Sholpan [36]

Answer:

24.2 centimeters

Step-by-step explanation:

for height = f(time)

let x be the value of the height at 28hours

solving linearly

(28 - 15)/(32 - 15) = (x - 19)/(12.2 - 19)

solving we have

13/17 = (x - 19)/6.8

0.7647 = (x - 19)/6.8

cross multiplying,

x - 19 = 5.2

x = 5.2 + 19 = 24.2centimetres

L=w+4m
A=w*l
A=w(w+4)=45
w^2+4w-45=0
w^2+9w-5w-45=0
w(w+9)-5(w+9)=0
(w+9)(w-5)=0

⇒ w+9=0 or w-5=0
⇒w-5=0
w=5
l=5+4
l=9
