-x - 9
You want to get x by itself.
First subtract 9 from both sides of the equation.
-x - 9
+9 +9
-x
Then divide -1 on both sides.
-x/-1
I'm pretty sure when you divide a negative number when solving inequalities, you switch the sign.
x
16.76 rounds off to 17
After the dot if it’s 1-4 then they it would’ve been 15
5-9 is 17
If < A and then m< A + m/B = 90°, then D. Definition of Complementary Angles
<h3>What is a complementary angle?</h3>
When the sum of two angles is 90°, the angles are said to be complementary. In other words, if two angles add up to form a right angle, they are called complementary angles. The two angles are said to complement each other in this context.
Supplementary angles are two angles that add up to 180 degrees, whereas complementary angles are two angles that add up to 90 degrees.
An angle measuring 72 degrees has a complement of 18 degrees.
Therefore, based on the information given, the correct option is D.

Answer:
<em>The second choice is correct. It can be factored as:</em>
Step-by-step explanation:
<u>The Difference of Squares Method for Factoring</u>
The expression:
Is a widely used method to factor binomials that are expressed as the subtraction of two perfect squares.
The condition for a binomial to be factored by using this method is that both terms must have an exact square root and they must be subtracted.
The last two choices are not valid because they are not a subtraction but an addition.
The first choice is not valid because none of the terms is a perfect square.
The second choice is correct. It can be factored as:
