Lucy is playing a game at the school carnival. There is a box of marbles, and each box has a white, a green, a red, and an orang
e marble. There is also a fair 6-sided die numbered 1 through 6. How many outcomes are in the sample space for pulling a marble out of the box and rolling the die?
The best step to do next is to add 80 to both sides of equation: 5 ( x² + 8 x ) + 80 = 14 + 80 and since 80 = 5 · 16 5 ( x² + 8 x + 16 ) = 94 Answer : B ) After that we will continue like this: 5 ( x + 4 )² = 94 ( x + 4 )² = 18.8 ... etc
