Answer:
32x + 80 = y (Question 10)
240 (Question 11)
9514 1404 393
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
14/6 fourteen sixths
2 2/6 two and two sixths
simplified 2 1/3 two and a third
all u do is multiply L*W*H
hope this helps
To solve an equation like this, we simply need to isolate the variable and simplify. We can do this by performing the reverse operations on both sides of the equation, so that it does not change the value of the equation but rather the form it is written.
a+5=-5a+5
+5a +5a
6a+5=5
-5 -5
6a=0
/6 /6
a=0
Therefore, in this equation, a=0.
