The square has a property of having all the sides equal. The rectangle on the other hand has its opposite sides equal. The larger side of the rectangle is called length and the smaller side is called breadth. The area of rectangle is the product of length and breadth i.e.

[tex]\rm Area\:of\:rectangle = Length\: \times Breadth[/tex]

The side of square for the given question is [tex]4\rm \: inches[/tex].

Let the side of square be [tex]\rm x[/tex]

Given:

Area of rectangle is 9 square inches.

Side of square is reduced by 3 and other side is enlarged by 5. Therefore, dimensions of the rectangle will be:

[tex]\rm Breadth = x - 3\\\\Length = x + 5[/tex]

[tex]\rm Area\:of\:rectangle = Length\: \times Breadth\\\\9 = (x + 5)(x -3)\\\\9 = x^2 + 5x -3x -15 \\\\9 = x^2 +2x - 15 \\\\0 = x^2 +2x-15-9\\\\0 = x^2+2x-24\\\\[/tex]

On factoring the equation:

[tex]\begin{aligned} \rm x^2 + 2x -24 &= 0\\\\x^2 + 6x - 4x - 24 &= 0\\\\x(x+6)-4(x+6) &= 0\\\\(x+6)(x-4)&=0\end[/tex]

On equating [tex]\rm (x +6)[/tex] and [tex](x-4)[/tex] with 0 we get:

[tex]x = -6\\\\x=4[/tex]

Since side of square cannot be negative, [tex]x = 4[/tex] is the only correct value.

Therefore the side of square is [tex]4 \:\rm inches[/tex].

Answer:

the woman has to live 1 mile from work to minimize the expenses

Step-by-step explanation:

Given the data in the question;

the distance within 9 miles ⇒ 0 < x > 9

Total costs Q = cx + 4c/( x + 1)

costs should be minimum  ⇒ dQ/dx = 0

⇒ d/dx [ cx + 4c/( x + 1) ] = 0

⇒ ( x + 1)² = 4

take square root of both side

√[ ( x + 1)² ] = √4

x + 1 = 2

x = 2 - 1

x = 1

Therefore, the woman has to live 1 mile from work to minimize the expenses

Step-by-step explanation:

Answer:

let's divide the figure in rectangle and triangle.

first we should find the area of triangle.

area of triangle =1/2×base×height

area of triangle=1/2×11cm×7cm

area of triangle=38.5cm²

area of rectangle =length ×width

area of rectangle =11cm×8cm

area of rectangle =88cm²

area of the figure=38.5cm²+88cm²

area of the figure=126.5cm²

Answer:

A. Distance KL = 7.36 m

B. Height ML = 4.25 m

C. The maximum height is 6.96 m

Step-by-step explanation:

A. Determination of distance KL

Hypothenus = KM = 8.5 m

Angle θ = 30°

Adjacent = KL =?

Cos θ = Adjacent / Hypothenus

Cos 30 = KL / 8.5

0.866 = KL / 8.5

Cross multiply

KL = 0.866 × 8.5

KL = 7.36 m

Thus, the distance is 7.36 m

B. Determination of height (ML)

Hypothenus = KM = 8.5 m

Angle θ = 30°

Opposite = ML =?

Sine θ = Opposite /Hypothenus

Sine 30 = ML /8.5

0.5 = ML / 8.5

Cross multiply

ML = 0.5 × 8.5

ML = 4.25 m

Thus, the height is 4.25 m

C. Determination of the maximum height.

Hypothenus = KM = 8.5 m

Angle θ = 55°

Opposite = ML =?

Sine θ = Opposite /Hypothenus

Sine 55 = ML /8.5

0.8192 = ML / 8.5

Cross multiply

ML = 0.8192 × 8.5

ML = 6.96 m

Thus, the maximum height is 6.96 m

Isolate the variable, note the equal sign, what you do to one side, you do to the other.

1) 4k = 24

Isolate the variable, k. Divide 4 from both sides of the equation:

(4k)/4 = (24)/4

k = 24/4

k = 6

2) 34 + h = 60

Isolate the variable, h. Subtract 34 from both sides of the equation:

34 (-34) + h = 60 (-34)

h = 60 - 34

h = 26

3) 1/5x = 30

Isolate the variable, x. Multiply 5 to both sides of the equation:

(5) * (1/5)x = (30) * (5)

x = 30 * 5

x = 150

4) m - 42 = 85

Isolate the variable, m. Add 42 to both sides of the equation:

m- 42 (+42) = 85 (+42)

m = 85 + 42

m = 127
