The difference of two squares factoring pattern states that a difference of two squares can be factored as follows:
So, whenever you recognize the two terms of a subtraction to be two squares, you can factor it as the sum of the roots multiplied by the difference of the roots.
In this case, the squares are obvious: is the square of , and is the square of
So, we can factor the expression as
(the round parenthesis aren't necessary, I used them only to make clear the two terms)
We can simplify the expression summing like terms:
Answer:
5
Step-by-step explanation:
multiplying each number with 5 will get you the next number
Answer:
P(E) =5/9
P(F)=P(E) × P(B<Y<R) = 5/54
Step-by-step explanation:
Let E be events that gives no two number on the dice
Probability P(E) = (6 × 5× 4 )/(6×6×6)
P(E) = 130/ 216 = 5/9
Probability P(B<Y<R) = 1/6
Probability P (F) = P(E) × P(B< Y < R)
P(F) = (5/9 )×( 2/6) = 5/ 54
Answer: 6
Step-by-step explanation:
0, 3, 4 , 6, 6, 7, 7, 9
6+6= 12
12 ➗ 2 = 6
The percentage discount given on the prove is not supplied ; Assume the percentage discount given on the phone is 60%
Answer:
0.4d
d - 0.6d
Step-by-step explanation:
Given that :
Percentage Discount given on phone = 60%
The discounted pice :
Initial percentage = 100%
Discount percentage = 60%
(100% - 60%) of price
(100% - 60%) * d
40%*d
0.4d
Also ;
(100% - 60%) * d
100%*d - 60%d
d - 0.6d
