Which of the following is a factor of 7x2 - 12x - 4? (6 points)
grin007 [14]

Answer:

We conclude that 'None of the above' is the correct answer.                    

Step-by-step explanation:

Given the expression

7x^2\:-\:12x\:-\:4

Breaking the expression into groups

7x^2\:-\:12x\:-\:4=\left(7x^2+2x\right)+\left(-14x-4\right)

Factor out x from 7x^2\:+\:2x

=x\left(7x+2\right)

Factor out -2 from \left(-14x-4\right)

=-2\left(7x+2\right)

so the expression becomes

7x^2\:-\:12x\:-\:4=\left(7x^2+2x\right)+\left(-14x-4\right)

                         =x\left(7x+2\right)-2\left(7x+2\right)

Factor out the common term 7x+2

                         =\left(7x+2\right)\left(x-2\right)

Therefore, from the given options, we conclude that 'None of the above' is the correct answer.

HELP!!! HELP!!! WILL GIVE BRAINLIEST
Nesterboy [21]

Answer:

(a) Two x plus eight is greater than negative four

(b) x > -6; number line would be an open circle at -6 and the line pointing in the positive direction to be shaded

Step-by-step explanation:

(a)

Note first that the inequality sign ">" means "greater than", so 2x + 8 > -4 in written language is:

<em>Two x plus eight </em><em>is greater than</em><em> negative four</em>

<em />

(b)

We solve this just like how we'd solve it if it were 2x + 8 = -4: isolate the variable first.

Subtract 8 from both sides:

2x + 8 - 8 > -4 - 8

2x > -12

Divide by 2:

x > -12/2

x > -6

So, the solution set is all numbers greater than -6.

Drawn on a number line, we would first place an <em>open circle</em> at -6 (because we are using > rather than ≥, which would include the -6 in the solution set). Then, because our solution set includes all numbers greater than -6, we shade in the part of the line that points in the positive direction, so it should include numbers like -5, -4, -3, -2, -1, 0, 1, 2, ... and so on.
