N= a number
2n= twice a number
If it's 43 less, then it would be 2n-43.
2n-43 is the answer.
Hope this helps! :)

Step-by-step explanation:
I do <u>not agree</u> that passing the state math and reading tests will be a predictor of a student's success in college.
<h3>What are the factors that determine a student's success
in college?</h3>
The factors that determine a student's success in college include the following:
- Students' attitudes to learning
- Teachers' attitudes to sharing knowledge
- Teaching methods for imparting knowledge
- Classroom learning environment
- Student's belief in gender stereotypes
- Parental factors.
<h3>Question Completion:</h3>
Do you agree with the board? Mention the factors that determine a student's success in college.
Thus, it is not necessarily true that passing the state math and reading tests will be a predictor of a student's success in college.

tan²(<em>θ</em>) - sin²(<em>θ</em>) = sin²(<em>θ</em>)/cos²(<em>θ</em>) - sin²(<em>θ</em>)
-- because tan(<em>θ</em>) = sin(<em>θ</em>)/cos(<em>θ</em>) by definition of tangent --
… = sin²(<em>θ</em>) (1/cos²(<em>θ</em>) - 1)
-- we pull out the common factor of sin²(<em>θ</em>) from both terms --
… = sin²(<em>θ</em>) (1/cos²(<em>θ</em>) - cos²(<em>θ</em>)/cos²(<em>θ</em>))
-- because <em>x</em>/<em>x</em> = 1 (so long as <em>x</em> ≠ 0) --
… = sin²(<em>θ</em>) ((1 - cos²(<em>θ</em>))/cos²(<em>θ</em>))
-- we simply combine the fractions, which we can do because of the common denominator of cos²(<em>θ</em>) --
… = sin²(<em>θ</em>) (sin²(<em>θ</em>)/cos²(<em>θ</em>))
-- due to the Pythagorean identity, sin²(<em>θ</em>) + cos²(<em>θ</em>) = 1 --
… = sin²(<em>θ</em>) tan²(<em>θ</em>)
-- again, by definition of tan(<em>θ</em>) --
