A rectangle has an area of 84 square feet. the length is twice the width. draw a rectangle and draw a line dividing it in two to
algol13

The width and length of the rectangle are 6.4 feet and 12. 96 meters respectively.

<h3>How to determine the dimensions</h3>

The formula for determining the area of a rectangle is expressed as;

Area = width × length

Given that;

  • Area = 84 square feet
  • length = 2w

Let's substitute into the formula

84 = w(2w)

84 = 2w²

Divide both sides by 2

84/ 2 = w²

42 = w²

Take square root of both sides

w = √42

w = 6.4 feet

Length = 2w = 2 × 6. 4 = 12. 96 meters

Thus, the width and length of the rectangle are 6.4 feet and 12. 96 meters respectively.

12 cos theta minus 16 sin theta is equal to zero find 2 sin theta + cos theta​
gayaneshka [121]

Answer:

2sinθ + cosθ = 2

Step-by-step explanation:

12 cos θ - 16 sinθ = 0

=> 3 cos θ -4 sin θ = 0

=> tanθ = 3/4

let P = 3x

B = 4x

=> H= 5x

=> sinθ = P/H = 3/5

cosθ = B/H = 4/5

2sinθ + cosθ

= 2× 3/5 + 4/5

= 6/5+4/5

= 10/5

= 2

=> 2sinθ + cosθ = 2

Find the roots of the quadratic equation x^2 – 8x = 9 by completing the square. Show your work.
loris [4]
X² - 8x = 9
x² - 8x - 9 = 0
x² + x - 9x - 9 = 0
x(x + 1) -9(x + 1) = 0
(x+1)(x-9) = 0
x = -1 or 9

In short, Your Answers would be -1 & 9

Hope this helps!
