Answer: the answer is (2,-4) if that's not the answer then can u post a full picture of the question
Step-by-step explanation:
One polynomial identity that crops up often in various areas is the difference of squares identity:
A2-b2=(a-b) (a+b)
We meet this in the context of rationalising denominators.
Sanjay, because quarts are twice as big as pints.
Step-by-step explanation:
Given
Milk quantity for Lisa = 3 quarts
Milk quantity for Sanjay = 12 pints
We have to convert both quantities in same unit so that we can compare both quantities.
We know that there are two pints in a quart.
So,
Lisa will have:
3*2 = 6 pints of milk
Hence,
Sanjay, because quarts are twice as big as pints.

Answer:
30 and 9
Step-by-step explanation:
x+y=39 , x-y=21
Solve for x:
x+y=39 , x-y=21
x= 30
Substitute x with 30:
(30)+y=39 , (30)-y=21
Solve for y:
y=9
As in each table can seat 8 people and the probability you need to find is about the first person you can ignore this data.
Probability that the first person to enter the room will be randomly seated at a maple table:
#maple tables: 9
# total tables: 9 +10 +5 +7=31
Then, the probability that the first person to enter the room will be randomly seated at a maple table is 9/31
