The average of 16 and x is 3. Find x.

IrinaK [193]

Answer:

x = - 10

Step-by-step explanation:

Average is calculated as

average = $\frac{sumofdata}{count}$ , thus

$\frac{16+x+3}{3}$ = 3

Multiply both sides by 3 to clear the fraction

19 + x = 9 ( subtract 19 from both sides )

x = - 10

Which choice represents the expanded form of the expression (x- 2)3

Murljashka [212]

Answer:

(x−2)^3=x^3−6x^2+12x-8

Step-by-step explanation:

if you are talking about the binomial (x−2)^3 you must expand then simplify. (x-2)3 you would just remove the parenthesizes and multiply -2 with 3 to get x-6 but I think you meant (x-2)^3
