Answer:

1. 4x^2 - x + 1.5

Step-by-step explanation:

1. The prism has 6 surface faces. 2 of the surfaces are marked. The third is not. The surface area of the prism is given. Subtract the areas you know from the total surface area and divide it by 2. The result is the area of the last surface face.

18x^2+12x+22 -(8x^2+10x+17) - (2x^2+4x+2)\\18x^2 + 12x + 22 -8x^2 -10x - 17 - 2x^2 - 4x -2\\8x^2 - 2x + 3

Divide this in 2.

The area of the unknown face is 4x^2 - x + 1.5

worty [1.4K]

Answer:

a) No

b) Sí

Step-by-step explanation:

a) En la inauguración de unos Juegos Olímpicos, los 38 representantes de una nación quieren desfilar en columnas de 6, ¿es posible?

Esto se calcula como

38 representantes / 6 columnas

= 6 2/6 = 6 1/3 columnas

No, no es posible, tendríamos 7 columnas con 6 columnas con representantes iguales de 6 y la séptima columna tendría solo 2 representantes allí

b) ¿Cómo podrían desfilar en columnas iguales?

Sí pueden

Esto se calcula como 38 representantes ÷ 2

= 19 columnas

Podemos tener 19 columnas con 2 representantes cada una

Well you add 1/2  + 1/2 = 1 in
(1/2+1/2) + (1/2+1/2) + (1/2+1/2) + (1/2+1/2) + (1/2+1/2) + 1/2=
    2 half inches per parentheses pairs which is 5 plus the 1/2 inch
