Answer:
C
Step-by-step explanation:
Ounces held by cooler devide by ounces held by a pitcher since we want to find how many pitchers goes to the cooler
Answer:
Given below
Step-by-step explanation:
The algebraic identity is (a-b)^2
= a^2 + b^2 - 2ab
So it'll be,
(x-4)^2
= x^2 + (4)^2 - (2)(x)(4)
= x^2 -8x + 16
or x^2 +16 -8x
<em><u>Question:</u></em>
For which value(s) of x will the rational expression below be undefined? Check all that apply.
(x-3)(x+6)/x+7
<em><u>Answer:</u></em>
For x = -7 the rational expression is undefined
<em><u>Solution:</u></em>
<em><u>Given rational expression is:</u></em>

We have to find the value of x for which the rational expression becomes undefined
A rational expression is undefined when the denominator is equal to zero
Here, the denominator becomes zero when x = -7
Substitute x = -7 in given

Thus for x = -7 the rational expression is undefined
