Answer:
2.3
Step-by-step explanation:
move the decimal to the right two times
If x = 3 is a solution, (x - 3) is a factor of f(x).
2x³ + x² - 25x + 12 ÷ (x - 3) [by long division] = 2x² + 7x - 4
so f(x) = (x - 3)(2x² + 7x - 4)
f(x) = (x - 3)(2x - 1)(x + 4)
so 'zeros', or more correctly solutions, are: x = 3, x = 1/2 and x = -4.
[by setting each of the factors equal to 0 and solving for x].
Set up a proportion

x is the estimated number of returned phones. cross multiply to find x
12 x 2000 = 24000
350 x X = 350x
24000=350x
Divide
x=68.57
B.) 68
Answer:
True
Step-by-step explanation:
The absolute value of -12 is 12 so both numbers are equal.
have a nice day :)
65% as a fraction is 65/100 which can also be reduced to 13/20
