Answer:
Step-by-step explanation:
To factor the expression, remove the greatest common factor or GCF from each term. Both terms share in common xy. The expression becomes:
What remains in the parenthesis is a different of perfect squares. Factor the difference of perfect squares into two binomials of the form (x+a)(x-a) where a is the square root of 
.
So the expression becomes:
Answer:
Step-by-step explanation:
= 12 - 3
= 9
= -8 - 4
= -12
= -60 + 12
= -48
= -2 + 2
= 0
= 17
= 1
Answer: E) 1/5
Step-by-step explanation:
The probability of any member being selected for each of the 3 posts is 1/10 that is they have equal probabilities of being selected for any of the posts.
The probability that harry would be selected for;
Secretary Ps= 1/10
Treasurer Pt = 1/10
So the probability of being selected for either secretary or treasurer is
P = Ps + Pt
P = 1/10 + 1/10
P = 2/10
P = 1/5
Note: ignore the sequence of selection
