Between which two consecutive integers does 249 lie?
GREYUIT [131]
If you are looking for the sum of two consecutive integers, there is a quick way to get the answers. Divide the number by two and you will find your answers.
249/2 = 124.5
Your two consecutive numbers are 124 and 125.
124 + 125 = 249.
If you mean by the square root of 249, your answers are 15 and 16; 15^2 = 225, 16^2 = 256. I hope this helps!

Find two numbers whose sum is 55 and whose product is 646​
Svet_ta [14]

Answer:

17 and 38

Step-by-step explanation:

x + y = 55......x = 55 - y

x * y = 646

y(55 - y) = 646

55y - y^2 = 646

y^2 - 55y + 646 = 0

(y - 17)(y - 38) = 0

y - 17 = 0       y - 38 = 0

y = 17            y = 38

ur numbers are 17 and 38

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
