What is the excluded value of x for the expression (x-4)^2/(x-9)^2

The excluded value of x = 9

Step-by-step explanation:

Since the Excluded values are the values that will make the denominator of a fraction equal to 0.

Because when the denominator of a rational function equals to zero it makes it infinite.

This is why we always exclude the value from the function.

Here The given expression,

Thus, for excluded value,

⇒ x - 9 = 0 ( by taking the square root on both sides)

⇒ x = 9 ( by adding 9 on both sides )

Thus, 9 is the excluded value for the given function.

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.
