Now we use FOIL to rewrite the expression.
FOIL is:
First
Outer
Inner
Last
That's the order we will be distributing the variables in the parentheses.

Combine like terms:

That's your final answer.
Hope that helps.
Solution:
Distance between two points = √(3−4)^2+(−2−3)^2
= √(−1)^2+(−5)^2
= √1+25
= √26
= 5.099
Distance between points (4, 3) and (3, -2) is 5.099.
Answer:
Step-by-step explanation:
From the table you can see that
- 45 customers own cat and dog;
- 78 own only cat, then 78+45=123 customers own cat;
- 125 own only dog, then 125+45=170 customers own dog;
- 52 own neither cat, nor dog;
- 78+45+125+52=300 customers in total;
- 300-123=177 customers do not own cat;
- 300-170=130 customers do not own dog.
