Answer:
64,9
Step-by-step explanation:
From my understanding the pattern would be:
Every other number is the next consecutive odd number,
( 1, 3, 5, 7 ) are all of the consecutive odds. (So the next odd is 9. )
That when we get to the part of where we get every other number for the remaining numbers, if you multiply the next even number by itself (square it).
4, 16, and 36 ( they are all perfect squares. )
They are the perfect squares of ( 2, 4, and 6) . So it makes sense that ( 8 ) is the next even number and you would square that and get ( 64 )
I hope this makes sense!!
Answer:
Step-by-step explanation:
For this case we have the following expression:
<span>
By properties of exponents we have:
Same basis, the exponents are added.
We have then:
Then, rewriting the exponent we have:
Therefore, an exponent to rewrite the expression is:
2
Answer:

Answer:
60 seconds.
Step-by-step explanation:
We have been given that Maria train can go around the track in 10 seconds. Alma train can go around the track in 12 seconds.
To find the number of seconds after which both trains will cross the finish line together the first time we will find LCM of 10 and 12. LCM will give us the smallest positive integer that is divisible by both 10 and 12.
Multiples of 10 are: 10, 20, 30, 40, 50, 60, 70,...
Multiples of 12 are: 12, 24, 36, 48, 60, 72, 84,..
We can see that least common multiple of 10 and 12 is 60, therefore, it will take 60 seconds for both trains to cross the finish line together the first time.
Parallelogram so
CD = AB
18x - 5 = 15x + 4
3x = 9
x = 3
answer
x = 3
