(x + x² + 4x) 3
3(x) + 3(x²) + 3(4x)
3x + 3x² + 12x
Answer:
648
Step-by-step explanation:
5832÷9=648
I'm not sure what else to put for the explanation.
20 nickels = 1 dollar
So, do 20 x 17.
20 x 17 = 340 nickels which is $17.
The answer is 340 nickels!
The answer would be 180 degrees
5x + 10y = 18
x = y -6, we substitute this into first equation.
5x + 10y = 18
5*(y - 6) + 10y = 18
5y - 30 + 10y = 18
So it the last option from the top.
