The only way to solve if it is equal to something
assuming that the teacher wanted you to make it equal to zero do
0=-3x^2-21x-54
remember if we can do
xy=0 then assume x and y=0
so factor
0=-3x^2-21x-54
undistribute the -3
0=-3(x^2+7x+18)
remember 0 times anything=0 so
x^2+7x+18 must equal zero
use quadratice formula which is
if you have
ax^2+bx+c=0 then
x=
x^2+7x+18
a=1
b=7
c=18
x=
x=
x=
i=√-1
x=
the zerose would be
x=

Total cost of canvas required in making the tent is rupees 79128
<em><u>Solution: </u></em>
Given:
Height of the cylindrical tent = h = 3.3 m
Diameter of it's base = d = 100m
r = 50 m
<em><u>Curved surface area of cylinder:</u></em>
Thus Curved surface area of cylinder = 1036.2 square meter
<em><u>Curved surface area of cone:</u></em>
Thus Curved surface area of cone = 8854.8 square meter
<em><u>Total curved area of tent:</u></em>
⇒ curved area of cone + curved area of cylinder
Thus total curved area of tent = 9891 square meter
<em><u>find total cost of canvas required in making the tent:</u></em>
The cost of canvas is 8 rupees per square meter
Thus total cost of canvas required in making the tent is rupees 79128
