hope this helps.
Think it is the 8 ticket deal cuz it has more but for me it really depends on what I am going to buy them for.
Hope this helps God Bless
Answer: The required probability is 
Step-by-step explanation:
Since we have given that
Number of spruce tree = 20
Number of maple tree = 50
Total trees = 70
We need to find the experimental probability that the next tree Colleen to get a spruce tree.
So, the probability would be :

Hence, the required probability is 
Answer:
explanations: we multiply with a rational surd
(x-9)*√(x+9)/(√(x-9)*√(x+9)
=(x-9)√(x+9)/

B.( x-9)/√x+3 =( x-9)*(√x-3)/(√x+3)*(√x-3)
= (x-9)*(√x-3)/x-9
=√x-3

Given:

Step 1
Suppose x= -3, then
x+ 3
Step 2
Divide the polynomial by (x+ 3)
Step 3
Determine the remainder and quotient from the above.
Quotient = x²+ x - 3
Remainder = 13
ANSWER
Quotient = x²+ x - 3
Remainder = 13
