Answer:
Option 2 is correct that is
and
and 
Step-by-step explanation:
We have been given with the expression 
We will simplify the given expression by factorisation we will get
Taking x as common from first two terms in numerator and 2 from last two terms in numerator
Similarly, take x common from first two terms and 9 from last two terms in denominator we will get

After arranging the terms we will get 
Taking out the common factor which is (x-12) from numerator and denominator it will get cancelled we will get

Hence, Option 2 is correct that is
and
and 
Answer:
Area of Mrs. Rockwell's lot is equal to the area of Mr. Brown's lot
Step-by-step explanation:
We can suppose the dimensions of Mrs. Rockwell's lot to be:
Length = x
Width = y
Then, we can write the dimensions of Mr. Brown's lot as:
Length = half as long as Mrs. Rockwell's lot
Length = 0.5x
Width = twice as wide as Mrs. Rockwell's lot
Width = 2y
Area of Mrs. Rockwell's lot = Length * Width
= x*y
Area of Mrs. Rockwell's lot = xy
Area of Mr. Brown's lot = 0.5x*2y
Area of Mr. Brown's lot = xy
<u>Area of Mrs. Rockwell's lot </u><u>is equal</u><u> to the area of Mr. Brown's lot, as calculated above</u>.
Answer:
a) 0.1818
Step-by-step explanation:
Given that:
The odd that it'll snow tomorrow is 9 to 6
The probability that it will snow tomorrow 

= 0.6
The probability that it'll not snow tomorrow 


= 0.4
Let assume that the odd that it'll snow tomorrow is 9 to 2
The probability that it will snow tomorrow 

= 0.8181
The probability that it'll not snow tomorrow 


= 0.1818
