The value of |x| + 2 is always positive and greater than |x|.
The correct question is as below:-
Use complete sentences to explain why |x| + 2 > |x|.
<h3>What is an expression?</h3>
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division.
The given expression is as follows:-
|x| + 2 > |x|.
Here x is in the mode so any number either negative or positive it will always give you a positive number. For an example put x = -5 in the above expression.
|-5| + 2 > | -5 |
5+ 2 > 5
7 > 5
Put -1 at the place of x
|-1| + 2 > |-1|
1 + 2 > 1
3 .> 1
As we can see in the above two examples for every value of x there will be a positive number and the value of |x|+2 is always greater than |x|.
Therefore the value of |x| + 2 is always positive and greater than |x|.

Answer:
152 photons
Step-by-step explanation:
Data provided in the question:
wavelength of the green light, λ = 550 nm = 550 × 10⁻⁹ m
Total energy = 5.50 × 10⁻¹⁷ J
Now,
Energy =
here,
n = number of photons
h = Plank's constant = 6.63 × 10⁻³⁴ J.s
c = speed of light = 3 × 10⁸ m/s
Therefore,
5.50 × 10⁻¹⁷ J =
or
( 5.50 × 10⁻¹⁷)( 550 × 10⁻⁹) = n(6.63 × 10⁻³⁴)(3 × 10⁸)
or
3025 × 10⁻²⁶ = n(19.89 × 10⁻²⁶ )
or
n = 152.086 ≈ 152 photons
