(pic attatched please help)Find the least common denominator for
these two rational expressions.

Step-by-step explanation:

n² -4n+ 4

Sum = -4

Product = 4

Factors :  -2 , -2

n² - 4n +4 = n² - 2n - 2n + (-2)*(-2)

                = n(n - 2) - 2(n - 2)

               = (n - 2) (n - 2) = (n - 2)²

n² - 7n + 10

Sum = -7

Product = 10

Factors:  -5 , -2

n² - 7n + 10 = n² - 5n - 2n + (-5)*(-2)

                   = n(n-5) - 2(n -5)

                  = (n - 5)(n-2)

n² - 4n +4 = (n-2)²

n² - 7n + 10 = (n - 5)( n-2)

Least common denominator =  (n -2)² (n-5)

function 2 has a greater rate of change than function 1

function 2 has a greater y-intercept than function 1

step-by-step explanation:

76%

step-by-step explanation:

24% are dogs and the remaining is 76% because 100-24=76
