6x2 is not 66, you would need to multiply by 11 instead of 2 because 6x11 is 66 thus getting the correct answer!!!! Hope this helps.

I need both of these.
Harman [31]

Answer:

Step-by-step explanation:

First method: for (x+3)^2 if you multiply (x+3)(x+3) you get x^2+6x+9 which doesn't equal x^2+9

Second way:  plug in a variable for example (2+3)^2= 25 and 2^2+9=13 so 13 doesn't equal 25

jada is using a computer’s random number generator to produce 6 random whole numbers between 1 and 100 so she can use a random s
nikdorinn [45]

Step-by-step explanation:

The random numbers are selected randomly. Just because they happen to be 6 numbers in a row does not mean that they were not. If she is confident in the random number generator, which can be assumed, then the random numbers were still randomly selected and can be used.

professor190 [17]

Answer:

El área del foso es 5.5 m²

Step-by-step explanation:

Hola!

Por favor, mira el esquema adjunto para una descripción del problema.

Viendo la figura, podemos deducir que el área del foso será igual al área del rectángulo formado por el jardín y el foso menos el área del jardín.

Área del foso = área del foso y jardín - área del jardín.

El área de un rectángulo se calcula multiplicando la longitud de la base por la altura:

Área del jardín = 2.5 m · 2 m = 5 m²

Área del rectángulo jardín - foso = 3.5 m · 3 m = 10.5 m²

Área del foso = 10.5 m² - 5 m² = 5.5 m²

El área del foso es 5.5 m²
