We need to start from the innermost parenthesis and work our way out.
The first parenthesis is 
. These are not like terms because one involves a variable, while the other is a constant term. Two terms are summable if they involve the same power(s) of the same variable(s).
So, we can take one step outwards, and we arrive to the square brackets. We have
and 2z and -13z are like terms, so we can sum them:
Finally we arrive to the whole expression, which is
Because, again, 5z and 11z were like terms.
Answer: B
Step-by-step explanation:
B is the only one of the tables that goes up with a order
Answer:
3.2*10^8>1.2*10^8>7*10^5>5*10^3
Step-by-step explanation:
5*10^3 = 5000
3.2*10^8=320000000
1.2*10^8=120000000
7*10^5=700000
320000000>120000000>700000>5000
therefor
3.2*10^8>1.2*10^8>7*10^5>5*10^3
Answer: -30
Step-by-step explanation:
My answer is correct because, All you have to do is subtract all the numbers by 11 and the one that has the sum -19 is the correct choice. In this case -30 does and we can make sure were orrect by subtracting 11 by -19 and that equals -30.
