Step-by-step explanation:
We want to select all the terms that are not considered to be like terms with
.
The terms that are like terms with
must have
.
It doesn't matter the coefficient.
So we can easily see that all the following are not like terms with
:



6(3+4) is the right answer because when you distribute you get 18+24.
Hope this helps!!
Answer:
At end of summer, the Maple is 19.44 feet
Step-by-step explanation:
We need to find 8% of 18 feet and add it to 18 to get the new height.
To get percentage to decimal, we need to divide by 100. Hence
8/100 = 0.08
8% of 18 is:
18 * 0.08 = 1.44 feet
Now, we need to add this to 18 feet. We have:
18 + 1.44 = 19.44 feet
The answer is zero hope that helps

Answer:
970
Step-by-step explanation:
It turns out that the radical terms cancel, so the result is an integer. You can find the integer value using your calculator. It is ...
(5 +2√6)³ +1/(5 +2√6)³ = 970
_____
The cube of 'a' is ...
(5+2√6)³ = 5³ +3·5²·2√6 +3·5·(2√6)² +(2√6)³
= 125 +3·50√6 +3·120 +48√6
a³ = 485 +198√6
The reciprocal of this is ...
b³ = 1/a³ = 1/(485 +198√6) = (485 -198√6)/(485² -6·198²) = (485 -198√6)/1
b³ = 485 -198√6
Then the sum is ...
a³ +b³ = (485 +198√6) +(485 -198√6) = 970
