Answer:
32 weeks.
Step-by-step explanation:
Let w represent number of weeks.
We have been given that the new plan will have the office recycling 1 kilogram of paper each week. So kilograms of paper recycled in w weeks would be 
.
We are also told that Toby's office had already recycled 7 kilograms. So total kilogram of paper recycled in w weeks would be 
.
Since Toby's office has to recycle a total of 39 kilograms of paper, so we will equate 39 with paper recycled in w weeks as:
Therefore, it will take 32 weeks for Toby's office to recycle a total of 39 kilograms of paper.
Answer:
You have three card : 3, 4, and 5.
You first pick one card randomly, the probability of picking a 3 is:
P = 1/3
You then pick a second card without putting the first card back, the probability of picking a 5 is:
P = 1/2
=> The probability of picking a 3 and then picking a 5:
P = (1/3) x (1/2) = 1/6
Hope this helps!

Answer:
-1
Step-by-step explanation:
-2/3 - 1/3
Since the denominators are the same, we can combine the numerators
-3/3
Simplify
-1
Answer: 9x²-6x+5
Step-by-step explanation:
To find (gοf)(x), you want to plug f(x) into g(x). It is the same as g(f(x)).
g(f(x))=(3x-1)²+4 [distribute by FOIL]
g(f(x))=9x²-6x+1+4 [combine like terms]
g(f(x))=9x²-6x+5
Now, we know that (gοf)(x)=9x²-6x+5.
Factors of the given expression by splitting middle term of expression
will be 
.
Given expression is
<h3>What is a factor?</h3>
A factor is a number that divides another number leaving no remainder
After we split 42x into 21x each,
The expression looks like,
Taking 3x+7 as common
So factors will be (3x+7) and (3x+7).
Therefore,
Factors of the given expression will be .
