Step-by-step explanation:
:)
The answer is B. x = 12
First, you must set up the equation.
Then, you must subtract 6x on both sides.
Next, subtract 11 on both sides.
Finally, divide -2 on both sides.

Answer:
(x - 7)(x + 3) = 0
Step-by-step explanation:
To factorise the quadratic
Consider the factors of the constant term (- 21) which sum to give the coefficient of the x- term (- 4)
The factors are - 7 and + 3, since
- 7 × 3 = - 21 and - 7 + 3 = - 4, thus
(x - 7)(x + 3) = 0 ← in factored form
