Answer:
The factors of the 7x² - 12x - 4 = 0 are (7x + 2)(x -2) .
Option (b) is correct i.e none of the above .
Step-by-step explanation:
As the expression given in the question.
7x² - 12x - 4 = 0
7x² - 14x + 2x - 4 = 0
7x (x - 2) + 2(x - 2) = 0
(7x + 2)(x -2) = 0
Thus the factors of the 7x² - 12x - 4 = 0 are (7x + 2)(x -2) .
Option (b) is correct i.e none of the above .
3.95m + 8.95b = 47.65 ; <span>bought 3 magazines so m = 3
substitute m = 3 into the equation above
</span>3.95 (3) + 8.95b = 47.65
11.85 + 8.95b = 47.65
8.95b = 47.65 - 11.85
8.95b = 35.8
b = 35.8 / 8.95
b = 4
