Solve for x and then find the measure of ZB

Mathematics
1 answer:
VARVARA [1.3K]3 years ago
8 0

Answer:

Step-by-step explanation:

angle A = angle B (because they are alternate exterior angles)

8x+6=4x+38

8x-4x=38-6

4x=32

x=32/4

x=8

For angle A

8x+6

8*8+6

64+6

70

For angle B

4x+38

4*8+38

32+38

70

whats another way to write (s-6)(s+1) when s represents the side of a square and the equation represents the area of a rectangle
viktelen [127]

The another way to write (s - 6)(s + 1) is s² - 5s - 6

Step-by-step explanation:

Let us revise how multiply two binomial (a + b)(x + y)

  • Multiply the 1st terms
  • Multiply the 2nd terms
  • Multiply the nears and extremes, where nears are the 2nd term of first bracket and 1st term in the second bracket, the extremes are the 1st term in the first bracket and the 2nd term in the second bracket
  • Add the like terms if necessary

∵ The area of the square = (s - 6)(s + 1)

- To find the another way multiply the two brackets

∵ s × s = s²

∵ -6 × 1 = -6

∵ -6 × s = - 6s ⇒ nears

∵ s × 1 = s ⇒ extremes

- The terms - 6s and s are like terms, then add them

∵ - 6s + s = - 5s

∴ (s - 6)(s + 1) = s² - 5s - 6

∴ The area of the square = s² - 5s - 6

The another way to write (s - 6)(s + 1) is s² - 5s - 6

8 candles and 16 bars of soap. 

You can solve this by setting up a system of equations. 

x + y = 24
4x + 5y = 112

Una caja de 25 newtons se suspende mediante un cable con diámetro de 2cm¿cuál es el esfuerzo aplicado al cable?
Naddik [55]

El cable experimenta un esfuerzo axial de 79577.472 pascales por el peso de la caja.

<h3>¿Cómo calcular el esfuerzo aplicado sobre el cable?</h3>

La caja tiene masa y está sometida a un campo gravitacional, por tanto, tiene un peso (W), en newtons. Por el principio de acción y reacción (tercera ley de Newton), encontramos que el cable es tensionado debido a ese peso y su área transversal experimenta un esfuerzo axial (σ), en pascales.

Asumiendo una distribución uniforme de la fuerza sobre toda la superficie transversal de la cuerda, tenemos que el esfuerzo axial se calcula mediante la siguiente expresión:

σ = W / (π · D² / 4)

Donde:

  • W - Peso de la caja, en newtons.
  • D - Diámetro del área transversal de la caja, en metros.

Si sabemos que W = 25 N y D = 0.02 m, entonces el esfuerzo axial aplicado a la cuerda es:

σ = 25 N / [π · (0.02 m)² / 4]

σ ≈ 79577.472 Pa

<h3>Observación</h3>

La falta de problemas verificados en español sobre esfuerzos axiales obliga a buscar uno equivalente en inglés.
