If X + Y equal to 5 and x y equal to 6 find the value of x cube + y cube how

x³ + y³ = 35

Step-by-step explanation:

Using the following identities

(x + y)² = x² + 2xy + y² , then

5² = x² + y² + 2(6)

25 = x² + y² + 12 ( subtract 12 from both sides )

13 = x² + y² → (1)

x³ + y³ ← is a sum of cubes and factors as

x³ + y³ = (x + y)(x² - xy + y² )

           = 5(x² + y² - 6) ← substitute (1)

           = 5(13 - 6) = 5 × 7 = 35

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.

step-by-step explanation:

c) the median for town a 30" is greater than the median for town b 25"

step-by-step explanation:

town a, median = q2 = 30

town b, median - q2 = 25

so the median for town a 30" is greater than the median for town b 25"
