Answer:

(5x - 3)(7x + 4) .

Step-by-step explanation:

35x^2 - x - 12​

= 35x^2 - 1x - 12

Now we multiply the first coefficient by the last:

35 * -12 =  -420.

We need 2 values whose product is -420 and whose sum = the coefficient of x  ( -1).

These are 20 and -21, so we rewrite the original expression as:

35x^2 + 20x - 21x - 12      Now we try to  factor by grouping

5x(7x + 4) - 3(7x + 4)         7x + 4 is common so we have:

(5x - 3)(7x + 4)  (answer).

Sav [38]

<u>Answer:</u>

The correct answer option is 'Every tenth student in the main hallway between class.'

<u>Step-by-step explanation:</u>

Every tenth student in the main hallway between class would best represent the sample population since majority of the students transit this hallway unlike the rest of the options.

For instance, polling every tenth student in the library at lunch would result in the favor of views of students who frequently visit the library and polling every tenth student in the student section at the school football game would go in favor of those who prefer sports.
