Step-by-step explanation:
1 Expand by distributing terms.
rx+r×2
2 Regroup terms.
rx+2r
#7 is A
For # 5 & 6 is there a multiplication sign between the numbers or is supposed to be a power or something else?
The expression 12xyz - 45 is a binomial because there are two terms that is being separated by the operation '-'. 12xyz is one term; 45 is another term. That makes two terms. Binomial is a polynomial with 2 terms.
In order to answer this question, you need to know how many hours
there are in one day. After that, it's a piece-o-cake.
1 day = 24 hours .
Now you can make a table:
1 day = 24 hours
2 days = 48 hours
3 days = 72 hours
4 days = 96 hours
5 days = 120 hours
6 days = 144 hours
7 days = 168 hours
8 days = 192 hours
9 days = 216 hours
10 days = 240 hours
Moving left subtracts from the x value the number you move.
In (2,9) the x value is the number 2
You move 1 unit to the left so subtract 1 from 2:
2-1 = 1
You will be at (1,9)
