Mathematics
1 answer:
icang [17]4 years ago

Answer:

Step-by-step explanation:

First we rewrite the expression:

 3sec (x) -2 = 1

 3 (1 / cos (x)) -2 = 1

 3 (1 / cos (x)) = 1 + 2

 3 (1 / cos (x)) = 3

 (1 / cos (x)) = 3/3

 cos (x) = 1

 x = 2 * pi * n

 on the interval [0, 2pi):

 x = 0

 Answer:

 x = 0 on the interval [0, 2pi)

The length of a rectangle is 3 inches more than its width. If the perimeter is 42 inches, find the dimensions of the rectangle.​
aalyn [17]

P = 2w + 2l where w is the width, and l is the length. We know the length (l) is 3 inches longer than it's width (or l = w+3). Substitute w +3 into Perimeter equation. P = 2w + 2(w+3).
