Ponderosa Paint and Glass carries three brands of paint. A customer wants to buy another gallon of paint to match paint she purc
hased at the store previously. She can't recall the brand name and does not wish to return home to find the old can of paint. So she selects two of the three brands of paint at random and buys them. Her husband also goes to the paint store and fails to remember what brand to buy. So he also purchases two of the three brands of paint at random. Determine the probability that both the woman and her husband fail to get the correct brand of paint. (Hint: Are the husband's selections independent of his wife's selections

Answer:
7
Step-by-step explanation:
Answer:
x= "a certain number of inches"
side a= x-3
side b= 2 inches
multiply:
Area= a(b)
A= (x-3)2
A= 2(x-3)
distribute:
A= 2(x-3)
A= (2*x) + (2*-3)
A= 2x-6
Area= 2(x-3)
Area= 2x-6
Step-by-step explanation:
The area of the rectangle is equal to the multiple of its two sides this is equal to two inches times an expression three less than a certain number "x". Using the distributive property, we can solve this expression further to find that the area of this rectangle is also equal to six less than doubling a certain number x.
