Answer:

11 < x < 14

Step-by-step explanation:

<em>Bleach is said to have a pH of less than 14 and greater than 11.</em>

Let x = pH

First, we will consider individual inequalities.

  • Given x is greater than 11, 11 < x (this means that x takes values higher than 11, but not 11).
  • Given x is less than 14, x < 14 (this means that x takes values lower than 14, but not 14).

If we take both inequalities, we can set up a compound inequality: 11 < x < 14.

Answer:

The answer to your question is:     11 < pH < 14

Step-by-step explanation:

Data

Bleach have a pH  less than 14 and greater than 11.

We have to use these symbols:

                                                     <  greater than       >  less than

and pH will be  in the middle

                                          11 < pH < 14

This inequality means the Bleach has a pH between 11 and 14

Como se multiplican polinomios
seraphim [82]
I hope you speak english, because although i understood your question I don't know enough spanish to respond in it. You multiply polynomials by multiplying each part of one polynomial by all the other parts of the others, and then adding it all. For example: (ax+b) * (x+c) = (ax*x)+(ax*c)+(b*x)+(b*c) = a x^{2}  + acx + bx+bc
