Answer:
x = 9
Step-by-step explanation:
Solve for x:
x^2 - 18 x + 81 = 0
Write the left hand side as a square:
(x - 9)^2 = 0
Take the square root of both sides:
x - 9 = 0
Add 9 to both sides:
Answer: x = 9

The net weight of a jar of raspberry preserves will be 4.45 ounces.
The volume of the cylinder can be calculated as the product of the base of the cylinder and the height of cylinder.
The volume of cylinder= base of cylinder * height of the cylinder
⇒ volume of cylinder = πd²*h/4
Here, given that
the inside diameter of the cylinder is 1.5 inches.
d= 1.5 inches
the inside height of the cylinder is 4.75 inches.
h= 4.75 inches
putting these above values for calculating the volume of the cylinder
Volume =V = πd²*h/4
⇒ V= π*(1.5)²*4.75/4
⇒V = 8.40 cube inches
Given that the raspberry preserve weighs 0.53 ounces per one cubic.
for one cubic the weight is 0.53 ounces
for 8.40 cubic the weight will be 8.40*0.53= 4.45 ounces
Therefore The net weight of a jar of raspberry preserves will be 4.45 ounces.
