-(x+2); x CAN'T equal 2, because the denominator of the original fraction would be 0, which would make the term undefined.
The question has to do with scientific notation
<h3>What is scientific notation?</h3>
Scientific notation is the expression of a number in the form a × 10ⁿ where 1 ≤ a ≤ 10 and n is an integer.
<h3>How to simplify the expression?</h3>
Now to simplify the expression (9 × 10⁻¹³) - (6.3 × 10⁻¹⁵) both number have to have the same exponent to the power of 10.
So, re-writing, we have
(9 × 10⁻¹³) - (6.3 × 10⁻¹⁵) = (9 × 10⁻¹³) - (6.3 × 10⁻¹³ × 10⁻²)
= (9 × 10⁻¹³) - (6.3 × 10⁻² × 10⁻¹³ )
= (9 × 10⁻¹³) - (0.063 × 10⁻¹³ )
= (9 - 0.063) × 10⁻¹³ )
= 8.937 × 10⁻¹³
So, simplifying the expression (9 × 10⁻¹³) - (6.3 × 10⁻¹⁵) = 8.937 × 10⁻¹³

I’m guessing it would be 21/24
Answer:
89°
Step-By-Step Explanation:
<WYT is the angle 4
<UYW is the angle 5
since angle 4 and 5 are on the same line and
anngle 4 is 91°,
180° - 91° = 89°
This shows that <UYW is 89°
