Answer: the length is 6 feet. The width is 2 feet
Step-by-step explanation:
The garden pool is rectangular in shape.
Let L represent the length of the rectangular garden.
Let W represent the width of the rectangular garden.
The area of a rectangle is expressed as L× W. The area of the rectangular garden pond is 12ft^2. It means that
L× W = 12 - - - - - - - - - - 1
The length of the pool needs to be 2ft more than twice that width. This means that
L = 2W + 2 - - - - - - - - - - - 2
Substituting equation 2 into equation 1, it becomes
W(2W + 2) = 12
2W^2 + 2W = 12
2W^2 + 2W - 12 = 0
W^2 + W - 6 = 0
W^2 + 3W - 2W - 6 = 0
W(W + 3) - 2(W + 3) = 0
W - 2 = 0 or W + 3 = 0
W = 2 or W = - 3
Since the Width cannot be negative, then the width is 2 feet
Substituting W = 2 into equation 2. It becomes
L = 2×2 + 2 = 6 feet
Step-by-step explanation:
Interior angle + Exterior angle = 180°.
Size of Interior angle = 180° - 360°/n.
Question 32:
Exterior angle = 72°
Interior angle = 180° - 72° = 108°.
Therefore 180° - 360°/n = 108°, n = 5 => 5 sides.
Question 33:
Exterior angle = 36°
Interior angle = 180° - 36° = 144°.
Therefore 180° - 360°/n = 144°, n = 10 => 10 sides.
<em>Answer:</em>
<em>x = 1/2</em>
<em>Step-by-step explanation:</em>
<em>24x - 3 = 9</em>
<em>24x = 9 + 3</em>
<em>24x = 12</em>
<em>x = 12/24</em>
<em>x = 1/2</em>
