Sphinxa [80]

Answer:

x= +2\sqrt{5} or -2\sqrt{5}

Step-by-step explanation:

for the given equation,

4 - x^{2} = -16

using rules of equation and inverse operations as isolating x on one side of equation,

interchanging sides  of equation  we get,

x^{2} =20

x= +\sqrt{20} or x= -\sqrt{20}

x= +2\sqrt{5}  or x= -2\sqrt{5}

The organic garden at a restaurant is rectangular in shape and has a perimeter of 84ft. If the length of the garden is 24ft long
ArbitrLikvidat [17]

Answer: the area of the garden is 297 ft^2

Step-by-step explanation:

The organic garden at a restaurant is rectangular in shape and has a perimeter of 84ft. This means that the total distance around the restaurant is 84ft.

Perimeter of a rectangle is expressed as 2(L + W)

L = length of the rectangle

W = width of rectangle.

Since the perimeter is 84ft

2(L + W) = 84

If the length of the garden is 24ft longer than the width of the garden, this means that

L = W + 24

Therefore

2(W +24 + W) = 84

2(2W +24) = 84

4W + 48 = 84

4W =84 - 48 = 36

W = 36/4 = 9

L = W + 24 = 9+24

L = 33 feet

Area if a rectangle is expressed as

Area = L× W

Area = 33 × 9 = 297 ft^2

Write the ratio as a fraction in simplest form. 51 correct : 9 incorrect The ratio as a fraction in simplest form is.
Agata [3.3K]

Answer:

Ratio as a fraction in simplest form is, \frac{\text{17 correct}}{\text{3 incorrect}}

Step-by-step explanation:

Ratio defined as the relationship between the quantities of something i.e,

a: b = \frac{a}{b}

Given: 51 correct : 9 incorrect

By definition of ratio:

51 correct : 9 incorrect = \frac{\text{51 correct}}{\text{9 incorrect}}

Divide both numerator and denominator by 3 we get;

\frac{\text{17 correct}}{\text{3 incorrect}}

then

The ratio as a fraction in simplest form  is, 17 correct : 3 incorrect or \frac{\text{17 correct}}{\text{3 incorrect}}
