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

Answer:

c

Step-by-step explanation:

Since the perimeters are equal, then equate the perimeter expressions, that is

4(x - 2) = 6(\frac{1}{2} x + 5) ← distribute parenthesis on both sides

4x - 8 = 3x + 30 ( subtract 3x from both sides )

x - 8 = 30 ( add 8 to both sides )

x = 38

Substitute x = 38 into either of the 2 perimeter expressions

perimeter = 4(x - 2) = 4(38 - 2) = 4 × 36 = 144 in → c
