The answer is the first one.
Explanation:
X^3 stays the same because there are no other cubed numbers in the problem
Next you combine the x^2s
The x^2s are +3x^2 and +2x^2
Since they are both positive, you add them: 3x^2 + 2x^2 = 5x^2
Next you do the x values
-x and +6x, also known as 6x - x = 5x
Lastly, you just add in the -2 and get:
X^3 + 5x^2 + 5x - 2
the answer is 72

Answer:
D
Step-by-step explanation:
Let x = total number of basketball games that was played by the team this season.
Alon started in 60% of his team’s basketball games this season. This means that he started in a total number of 60 percent of x basketball games this season.
60% of x basketball games this season = 60/100 × x
= 0.6×x = 0.6x
From the information given, Alon started a total of 12 basketball games this season. Therefore,
0.6x = 12
x = 12/0.6 = 20
2(x - 4) + 7(x + 2)
mutiply the first bracket by 2
(2)(x)=2x
(2)(-4)= -8
mutiply the second bracket by 7
(7)(x)=7x
(7)(2)= 14x
2x-8+7x+14
2x+7x-8+14 ( combine like terms)
Answer:
9x+6 or 6+9x
They throw out the records they no longer need or seen unnecessary because they no longer see the importance of having it.
