X2 + -4 = 0
Reorder the terms:
-4 + X2 = 0
Solving
-4 + X2 = 0
Solving for variable 'X'.
Move all terms containing X to the left, all other terms to the right.
Add '4' to each side of the equation.
-4 + 4 + X2 = 0 + 4
Combine like terms: -4 + 4 = 0
0 + X2 = 0 + 4
X2 = 0 + 4
Combine like terms: 0 + 4 = 4
X2 = 4
Simplifying
X2 = 4
Take the square root of each side:
X = {-2, 2}</span>
The surface area of the pencil is the amount of space it covers
The surface area of the pencil is 61 square centimeters
<h3>How to determine the surface area?</h3>
The given parameters are:
H = 20 cm
L = 0.5 cm
The surface area (SA) is then calculated as:
SA = 6LH + 3
L^2
This gives
SA = 6 * 0.5 * 20 + 3
* 0.5^2
Evaluate the sum
SA = 61
Hence, the surface area of the pencil is 61 square centimeters

Answer:
.25, .012, .001
Step-by-step explanation:
Divide the length by 1000
25÷1000= .25
12÷1000= .012
1÷1000= .001
