Answer:
Step-by-step explanation:
To find this equation in standard form, first, write it in factored form. This looks like . Then, multiply the polynomials using the FOIL (First, Outside, Inside, Last) method.
- Following the FOIL method, you should multiply the first terms in each binomial, , which equals .
- Then, the outside terms, . This equals .
- Next, the inside terms, .
- Finally, the last terms, , this equals .
Then, add all of the terms together . To get the standard form, combine like terms, this comes out to .

Step-by-step explanation:
The answer choice which correctly models the range of pH values of bleach is; 11< x < 14.
<h3>What is.the range of values for the pH of bleach?</h3>
According to the task content; Bleach is said to have a pH of less than 14 and greater than 11.
Hence; pH < 14. and pH > 11.
Therefore, when written as a compound inequality; we have;
11< pH < 14.

Step-by-step explanation:
When in doubt, draw a diagram.
The orthocenter of this acute triangle will be within its bounds. That should tell you right away that the y-coordinate of it will not be 8, but must be between 2 and 6.
The line perpendicular to BC through A must have a y-intercept greater than the y-coordinate of A, so cannot be 5. Whatever it is, the y-coordinate of the orthocenter will be less, so again, your answer fails the reasonableness test.
The perpendicular line to BC through A is ...
... y = (-1/2)(x -2) +6 = -x/2 +7 . . . . . . looks like you had a sign error in (-1/2)(-2)
The intersection of that line and x=6 is ...
... y = -6/2 +7 = 4
