The excluded values are the values that the variable cannot take on because it makes the overall expression undefined.
For example, we can't have in the expression because is undefined.
For both of these problems you do the same sort of thing, with some factorization along the way:
If or , the denominator is 0 and we have an undefined expression, so these are the excluded values.
If or , we get an undefined expression.
Of means multiply
is means equals
1/2 • x = -.25
Rewritten
.5•x=-.25
Inverse operations to isolate the variable.
x = -.25/.5
x = -.5
Answer:

Step-by-step explanation:
<u>Divide 54 by 9 to represent 1:9.</u>
54 ÷ 9 = 6.
<u>Multiply 6 by 4 to represent 4:9.</u>
6 · 4 = 24.
<u>The perimeter of the smaller rectangle is 24 inches.</u>
