18, 42, and 27. they were all times by 2
Answer:
x = 30
Step-by-step explanation:
1/2(x+6) = 18
Distribute
1/2 x + 3 = 18
Subtract 3 from each side
1/2x +3-3 = 18-3
1/2x = 15
Multiply each side by 2
1/2x*2 = 15*2
x = 30
Withdrawals must be subtracted from the beginning balance since to withdraw means to take out, so withdrawing money would lower the balance.
Deposits are added to the balance, so they must be added in the equation.
The answer is <span>c) Beginning Balance - Withdrawals + Deposits = Ending Balance</span>
Answer:
A. Similar; congruent angles
Step-by-step explanation:
(x + 5)(x² - 3x)
Use FOIL (First, Outside, Inside, Last)
x(x²) = x³
x(-3x) = -3x²
5(x²) = 5x²
5(-3x) = -15x
Combine like terms:
x³ - 3x² + 5x² - 15x
x³ + 2x² - 15
x³ + 2x² - 15 is your answer
hope this helps
