Answer: x=0
Step-by-step explanation: f(x)=(x+2)x2-4
0=2x+4-4
0=2x
2x/2=0
0/2=0
x=0
Answer:
Step-by-step explanation:
A. The leading coefficient is the number on the highest degree term. We have a 2nd degree polynomial because of the power of 2 on the x. That's what leads this polynomial off. So the leading coefficient is the number stuck to that x-squared term. Our leading coefficient is a -.2, not 5. 5 is the linear term.
B. The constant is the number that doesn't have a variable stuck to it. Our constant, then, is -8, not 2.
C. The expression does in fact have 3 terms. Each term is separated from the other terms by either a plus sign or a minus sign. A polynomial with 3 terms is called a trinomial.
D. The expression actually factors to x = 1.718... and x = 23.281... Neither one of those is the factor given in the statement.
The only one that is true is C.

Answer:
The mean of the data set = 
Step-by-step explanation:
Please check the dot plot which is attached below.
As we know that we can determine mean from the dot plot by adding the numbers and then divide the resulting sum by the number of addends.
From the dot plot it is clear that:
So adding all the dots with respect to their values on the plot number by the total number of dots.
Thus
Mean = (1+1+1+2+2+2+2+3+3+3+4+4+4+4+5+5+5+5+5+6+6+6) ÷ 22
Hence, the mean of the data set =
