If tanx-cotx=5 then what is the value of tan²x+cot²x

Roman55 [17]

Answer:

Step-by-step explanation:

note that tanx cotx = tanx × $\frac{1}{tanx}$ = 1

Given

tanx - cotx = 5 ( square both sides )

(tanx - cotx)² = 5² = 25 ← expand left side using FOIL

tan²x - 2tanxcotx + cot²x = 25

tan²x - 2 + cot²x = 25 ( add 2 to both sides )

tan²x + cot²x = 27

A square has a perimiter of 12x +52 units which expression represents the side length of the square in units

8_murik_8 [283]

Answer:

Step-by-step explanation: One important property of a square is that all the sides of the square have the same length. That means, if a square has a perimeter of P, then one side must have a length of P/4 units. So for a square with a perimeter of (12x + 52) units, its sides would have a length of (12x + 52)/4 = (3x + 13) units. Therefore, the answer is C: (3x + 13) units.
