In 2012 there were approximately 8950 public librarys in the United States a survey found that 76% of the library's offered free access to the electronic books based on this information how many public library offered free access electronic books in 2012

6,802

Step-by-step explanation:

Our first step is to change 76% into a decimal:

76% -> -> 0.76

Next, lets multiply and solve for x:

There were 6,802 public libraries that offered free access electronic books in 2012.

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

i only know the sequence of arithmetic it adds the first is 5+4 then it goes up as it adds to then it is 9+5 then 14+6 then to 20+7 and so on. 5,9,14,20,27,35.
