Step-by-step explanation:
<u>Find zeros first:</u>
- x² + x - 6 = x² + 3x - 2x - 6 = x(x + 3) - 2(x + 3) = (x - 2)(x + 3)
- x = 2, x = -3, x = 7 (but x ≠ 7 as no division by zero)
<u>We have 4 intervals:</u>
- x ≤ - 3, three negatives, the result is negative or zero
- -3 ≤ x ≤ 2, two negatives and one positive, the result is positive or zero
- 2 ≤ x < 7, two positives and one negative, the result is negative or zero
- x > 7, three positives, the result is positive or zero
<u>The solution is:</u>
Correct choice is A
Answer:
<em>d = 6</em>
Step-by-step explanation:
Cross multiply.
2/9 = d/27
9d = 2 * 27
d = 2 * 3
d = 6
You can also think of finding an equivalent fraction. The left fraction has denominator 9. Multiply 9 by 3 to get denominator 27. Now multiply 2 by 3 t get 6. d = 6
