Answer:
B
Step-by-step explanation:
Part A:
3(m+54) = 381 shows that 54 is being added to m, the initial sum. Then it shows the sum of 54 + m being multiplied by 3 to get to the new balance of $381. This equation most accurately matches with the question.
Part B:
3(m-54) = 381.
You would first divide both sides by 3.
m - 54 = 127
You would now add 54 to both sides.
You now know m = 181.

<h3><u>(f - g)(x) = -2x^2 + 10x</u></h3>
x^2 + 6x - 1 - (3x^2 - 4x - 1)
Distributive -1 to each term in parentheses.
x^2 + 6x - 1 - 3x^2 + 4x + 1
Combine like terms.
-2x^2 + 10x
