What are the excluded values of x for x^2-9x/x^2-7x-18
2 answers:
The expression is 
.
The excluded values are those values of x for which the denominator,
, becomes zero.
So, we need to factorize the expression.
To factorize the expression, we can use the grouping method. Write -7x as -9x+2x to create 4 terms, as follows:
.
The, factorizing (x-9), we have (x-9)(x+2).
This expression becomes 0 for x=-2, or for x=9.
Answer: {-2, 9}

Answer:
y = 120
x = 10.6
Step-by-step explanation:
Given polygons are parallelograms.
In parallelograms, consecutive angles are supplementary which means their sum is equal to 180.
Since two parallelograms are similar:
60 + y = 180 subtract 60 from both sides
y = 120
To find the value of x:
side lengths are proportional because these are similar polygons
cross multiply fractions
18x + 72 = 264 subtract 72 from both sides
18x = 192 divide both sides by 18
x = 10.6 approximately
