12. Si R(x)=-5x2+x-2 y S(x)=-x - 3x, se<br>¿cuál es el resultado de R(x) + S(x) ?

lesya692 [45]

Answer:

El resultado eres: $R(x) + S(x) = -6x^2 - 2x - 2$

Step-by-step explanation:

Se dan las siguientes funciones

$R(x) = -5x^2 + x - 2$

$S(x) = -x^2 - 3x$

Cuál es el resultado de R(x) + S(x) ?

Se soman los fatores en comun. Entonces:

$R(x) + S(x) = -5x^2 + x - 2 + (-x^2 - 3x) = -5x^2 + x - 2 - x^2 - 3x = -5x^2 - x^2 + x - 3x - 2 = -6x^2 - 2x - 2$

El resultado eres: $R(x) + S(x) = -6x^2 - 2x - 2$

Use Julia’s work and finish finding the areas of the faces what is the surface area of the rectangular pyramid

hoa [83]

Answer:

The surface area of the rectangular pyramid is $SA=109.50\ m^{2}$

Step-by-step explanation:

we know that

The surface area of the rectangular prism is equal to the area of the rectangular base plus the area of the four triangular faces

$SA=(8)(5)+2[14.75]+2[\frac{1}{2}(8)(5)]$

$SA=40+29.50+40$

$SA=109.50\ m^{2}$
