Responder:
10 (2ny- (x-y))
Explicación paso a paso:
Dada la expresión 10ny-10x + 10ny + 10y, para simplificar la expresión, se deben seguir los siguientes pasos;
Paso 1; Separa la expresión en términos similares
= 10ny-10x + 10ny + 10y
= (10ny + 10ny) - (10x + 10y)
Paso 2: Factoriza los valores comunes en ambos paréntesis
10ny (1 + 1) - 10 (x-y)
= 10ny (2) - 10 (x-y)
= 20ny - 10 (x-y)
Factoriza nuestro valor común en ambos términos:
= 10 (2ny- (x-y))

Answer: Option D
Step-by-step explanation:
For a quadratic function of the form
The x coordinate of the vertice is:
In this case the function is:
So
The x coordinate of the vertice is:
The y coordinate of the vertice is:
The vertice is: (-3, -11)
The form e vertice for a quadratic equation is:
Where
the x coordinate of the vertice is h and the y coordinate of the vertice is k.
Then h=-3 and k =-11
Finally the equation in vertex form is:
Three hundred and twenty seven point seven nine
Answer:
m∠P = 70°, m∠T = 20°, m∠SKP = 40° , and m∠MKT = 70°
Step-by-step explanation:
* Lets explain how to solve the problem
- In Δ PST
∵ m∠S = 90°
∴ m∠T + m∠P = 90° ⇒ interior angles of a triangle
∵ m∠SPK/m∠KPT = 5/2
- The ratio between the two angles are 5 : 2 , multiply the parts of the
ratio by x, where x is a real number
∴ m∠SPK = 5x
∴ m∠KPT = 2x
∵ m∠SPK + m∠KPT = m∠P
∴ m∠P = 5x + 2x = 7x
- In ΔPKT
∵ KM ⊥ PT
∵ MP = Mt
∴ KM is perpendicular bisector of PT
∴ ΔPKT is an isosceles triangle with KP = KT
∵ KP = KT
∴ m∠KPT = m∠T
∵ m∠KPT = 2x
∴ m∠T = 2x
∵ m∠T + m∠P = 90°
∵ m∠P = 7x
∵ m∠T = 2x
∴ 2x + 7x = 90 ⇒ solve for x
∴ 9x = 90 ⇒ divide both sides by 9
∴ x = 10
∵ m∠P = 7x
∴ m∠P = 7(10) = 70°
∴ m∠P = 70°
∵ m∠T = 2x
∴ m∠T = 2(10) = 20°
∴ m∠T = 20°
- In ΔSKP
∵ m∠S = 90°
∵ m∠SPK = 5x = 5(10) = 50°
∴ m∠SKP = 180° - (90° + 50°) = 180° - 140° = 40° ⇒ interior angles of a Δ
∴ m∠SKP = 40°
- In Δ KMT
∵ m∠KMT = 90°
∵ m∠T = 20°
∴ m∠MKT = 180° - (90° + 20°) = 180° - 110° = 70° ⇒ interior angles of a Δ
∴ m∠MKT = 70°
