Answer:

\frac{ {x}^{2} +  - 4x - 2 }{ {x}^{2} - 4 }  +  \frac{8x + 6}{{x}^{2} - 4}  \\ =  \frac{ {x}^{2} +  - 4x + 8x - 2 + 6 }{ {x}^{2} - 4 } \\ =  \frac{ {x}^{2} +   4x  +  4 }{ {x}^{2} - 4 } \\  =  \frac{ {(x + 2)}^{2} }{(x - 2)(x + 2)}  \\  =  \frac{x + 2}{x - 2}

A rectangle is 5.1 cm wide and each diagonal is 9.3 cm long. What is the measure of the angle between a diagonal and the shorter
Anastasy [175]

Answer:

56.7°

Step-by-step explanation:

A rectangle is 5.1 cm wide and each diagonal is 9.3 cm long. What is the measure of the angle between a diagonal and the shorter side of the rectangle to the nearest tenth of a degree?

We solve this question using the Trigonometric function of Sine

From the question, we are told that:

A rectangle is 5.1 cm wide

and each diagonal is 9.3 cm long.

Since we have a diagonal, this means the shape is transformed to a triangle.

The width of the rectangle = Adjacent side of a triangle = 5.1cm

The diagonal of the rectangle = Hypotenuse = 9.3cm

Hence,

cosθ = Adjacent/Hypotenuse

cosθ = 5.1/9.3

cosθ = 0.5483870968

θ = arccos(0.5483870968)

θ = 56.743568714°

Approximately = 56.7°

The measure of the angle is 56.7°

The perimeter of the blueprint is represented by the equation P=8x. What is the equation of the perimeter when solved for x
Korvikt [17]

Answer:

x = P/8

Step-by-step explanation:

The perimeter of the blueprint is given by the equation :

P = 8x

We need to solve the above equation for x.

Dividing both sides of the equation by 8.

\dfrac{P}{8}=\dfrac{8x}{8}\\\\x=\dfrac{P}{8}

Hence, the value of x is P/8
