Answer:

Step-by-step explanation:

\frac{x+1}{x}-\frac{y+1}{y}=\frac{(x+1)*y}{x*y}-\frac{(y+1)*x}{y*x}\\\\=\frac{xy+y}{xy}-\frac{xy+x}{xy}\\\\=\frac{xy+y-(xy+x)}{xy}\\\\=\frac{xy+y-xy-x}{xy}\\\\=\frac{y-x}{xy}

(X^2-16)/(x^2)-x-12
Mariulka [41]
Answer: (x + 3)(x - 4)

Step-by-Step Solution:

We need to Factorize the given Quadratic Polynomial by using Splitting the Middle Term Method.

= x^2 - x - 12
= x^2 - 4x + 3x - 12
= x(x - 4) + 3(x - 4)
=> (x + 3)(x - 4)

What is the area in square centimeters of the trapezoid below​
Dovator [93]

Answer:

39.6 cm²

Step-by-step explanation:

The formula for the area of a trapezoid is given as:

Area of a Trapezoid = 1/2(a + b) h

Where, from the question:

a = 8.9 cm

b = 5.5 cm

h = 5.5cm

Hence,

1/2 (8.9cm + 5.5cm) × 5.5cm

= 1/2 × 14.4 cm × 5.5 cm

= 39.6 cm²

Area of the Trapezoid = 39.6 cm²

Need help<br> Given u = ⟨root3, -1⟩ and v = ⟨3, –4⟩, what is u · v?
Kryger [21]

Answer:

3\sqrt{3} + 4

Step-by-step explanation:

If u = < x₁, y₁ >  and v = <x₂ , y₂ > , then

u • v = x₁x₂ + y₁y₂

Given

u = < \sqrt{3}, - 1 > and v = < 3, - 4 >, then

u • v = 3\sqrt{3} + (- 1)(- 4) = 3\sqrt{3} + 4

Help with this question please​
Allisa [31]

Step-by-step explanation:

The LKM angle is an enclosed angle. So its size is half the arc facing it.

LKM (angle) = ½ LM (arc)

The LMN angle is a shadow angle. So its size is half the size of the arc facing it.

LMN(angle) = ½ LM(arc)

so:

LKM = LMN
