The answer is not d it’s b because there is no negative in the 144.
Answer:
Multiply the numbers in parentheses by 3.
Which gives you 12 + 6b - b =27
Combine like terms
12 + 5b = 27
Then subtract 12 from both sides
Which leaves you with
5b = 15
Divide both side by 5
which gives you
answer C
move all numbers to one side and variables to the other.
2x = 32 - 19 - 3
2x = 10
x = 5

Answer:
B. 9
Step-by-step explanation:
So when solving a question like this, you may try to find what 3⁴ is and what 3² is and divide, but there is a much easier way to do this. Remember:
This can be used to find without finding what 3⁴ is. This is how we would do it:
And now we get the solution, 9, which is answer choice B.
