If 5x = sec(θ) and 5/x = tan(θ), then x = sec(θ)/5 and 1/x = tan(θ)/5.

Then

5 (x² - 1/x²) = 5 ((sec(θ)/5)² - (tan(θ)/5)²)

… = 5 (sec²(θ)/25 - tan²(θ)/25)

… = sec²(θ)/5 - tan²(θ)/5

Recall that

sec²(θ) = 1 + tan²(θ)

Then

5 (x² - 1/x²) = (sec²(θ) - tan²(θ))/5 = 1/5

The area of a rectangle is 42 m2, and the length is
MrRissso [65]

Answer:

length = 14 m

width = 7 m

Step-by-step explanation:

l = length

w = width

l = 2w - 8

w(2w - 8) = 42

2w² - 8w - 42 = 0

you can factor out a 2 to work with smaller numbers:

w² - 4w - 21 = 0

(w - 7)(w + 3) = 0

w = 7

'w' cannot equal a negative so we discount it as an answer

find length:

l = 2(7) - 8

l = 14 - 8 or 6m
