Answer:

3(4+3^2)×8

Step-by-step explanation:

Evaluate the power

3(4+9)×8

Add the numbers 3×13×8

Calcuate the product and it will be 312

So the expression 3×(4+3^2)×8 are equivalent to 312

lora16 [44]

Answer:

x + √x - 6

Step-by-step explanation:

Multiply out (√x-2)(√x+3) using the FOIL method:

Multiply the First terms: x

Multiply the Outside terms: 3√x

Multiply the Inside terms: -2√x

Multiply the Last terms: -6

Now combine these results. We get:

What is the first step in solving the following equation

Naily [24]

Answer:

The first step in solving the equation is "set each binomial factor equal to zero" ⇒ 3

Step-by-step explanation:

To solve a quadratic equation y = ax² + bx + c

Put y = 0
Factorize it into two binomial factors (x ± m)(x ± n)
Equate each binomial factor by 0 to find the values of x
The values of x are the solution of the equation

∵ The equation is (x + 2)(x - 3) = 0

∵ The equation equated by 0

∵ It is factored into 2 binomial factors (x + 2) and (x - 3)

- The next step is equated each factor by 0 to find the values of x

∴ The 1st step in solving (x + 2)(x - 3) = 0 is set x + 2 = 0 and

x - 3 = 0

The first step in solving the equation is "set each binomial factor equal to zero"

Calificación mínima. Para obtener una A en un curso, Stephen Heasley debe

Snowcat [4.5K]

Answer:

La mínima calificación que Stephen puede recibir en el quinto examen para obtener una A en el curso es 98.

Step-by-step explanation:

La media (también llamada promedio o media aritmética) de un conjunto de datos es una medida de posición central. Es el valor obtenido al sumar todos los datos y dividir el resultado entre el número total de datos.

En este caso, el número total de datos es 5 y el valor de los datos de los cuales debes obtener el problema es 92, 87, 96, 77 y un valor desconocido de un quinto examen. Y sabes que este valor debe ser igual o mayor a 90.

Esto se expresa matemáticamente como:

$\frac{92+87+96+77+nota}{5}$ ≥90

donde "nota" es la mínima calificación que Stephen puede recibir en el quinto examen para obtener una A en el curso.

Resolviendo:

$\frac{352+nota}{5}$ ≥90

352+nota≥90*5

352+nota≥450

nota≥450 - 352

nota≥98

<u><em>La mínima calificación que Stephen puede recibir en el quinto examen para obtener una A en el curso es 98.</em></u>
