5 x (8 x 10 with the power of 4)
ella [17]
First you need to solve the stuff in the parenthesis.
8 x 10^4

10^4 = 10,000

8 x 10,000 = 80,000

80,000 x 5 = 400,000

The answer is 400,000

6. Complete la tabla con el número 4.956: Dígito Valor posicional Notación estándar Notación en potencia De esta forma el número
Rzqust [24]

Answer:

6. Miles  {}     cientos       decenas      unidades

  4   {}              9                5               6

7. Catalina podrá hacer un cuadrado con longitud lateral de 4 cartones

8. 45000000 = 4.5 × 10⁶

0.000000000000056 = 5.6 × 10¹⁴

0.000000000034 = 3.4 × 10¹¹

Step-by-step explanation:

6. Los valores posicionales de dígitos son;

Miles  {}     cientos       decenas      unidades

4   {}              9                5                   6

 

7. El número de cuadrados que tiene Fernando = 12

El número de cuadrados que tiene Catalina = 16

El largo y el ancho de un cuadrado son iguales, por lo tanto tenemos;

largo × ancho = Área del cuadrado

largo = ancho = lado del cuadrado

Lado del cuadrado × Lado del cuadrado = Área del cuadrado

(Lado del cuadrado) ² = Área del cuadrado

Lado del cuadrado = √ (Área del cuadrado)

Para Fernando, Área del cuadrado = 12

Lado del cuadrado para Fernando = √12 = 2 · √3 cartones

Para Catalina, Área del cuadrado = 16

Lado del cuadrado para Catalina = √16 = 4 cartones

Por tanto, Catalina podrá realizar un cuadrado con longitud lateral de 4 cartones

8. 45000000 = 4.5 × 10⁶

0.000000000000056 = 5.6 × 10¹⁴

0.000000000034 = 3.4 × 10¹¹

Find and simplify an expression for the area of two rows of b squares with side lengths of b centimeters. Please help!
Ronch [10]

Answer:

The complete area of the given figure is (2 b^3) cm^2

Step-by-step explanation:

Total number of rows = 2

Squares in each row = b

So, the total number of  squares in 2 rows = 2 x ( Squares in 1 row ) = 2 x  b

Also, side length of 1 square = b cm

As we know, AREA OF SQUARE  = SIDE x SIDE

So here, area of 1 square  = Side x side  = b cm  x b cm = (b^2) cm^2

⇒ The area of total (2b) squares  = 2 b x ( Area of  1 square)

= 2 b \times (b^2)  = 2 b^3

Hence, the complete area of the given figure is (2 b^3) cm^2

Margarita [4]
Expand
x²+6x-27=-27
add 27 both sides
x²+6x=0
factor
x(x+6)=0
set to zero

x=0

x+6=0
x=-6


x=0 or -6

answer is 0 since -6 is not listed
