Question 7: Choose the correct simplification of the expression (3x − 6)(2x2 − 4x − 5)
Answer:
7. 6x³ - 12x² + 12x + 15
Step-by-step explanation:
(3x-6)(2x² - 4x - 5)
3x • 2x² = 6x³
3x • -4x = -12x²
3x • -5 = -15
-6 • 2x² = -12x²
-6 • -4x = 24x
-6 • -5 = 30
combine terms
6x³ - 12x² - 15 - 12x² + 24x + 30
combine like terms
6x³ - 24x² + 24x + 15

Answer:
$15.6
Step-by-step explanation:
one bag= $1.95
8 bags = 8×1.95=15.6
so answer is $15.6.
Using shifting concepts, it is found that the correct option is:
- Vertical stretch, horizontal shift left, vertical shift up.
The original function is:

- The original function was multiplied by 2, hence there was a <em>vertical stretch</em> by a factor of 2.
, hence, there was an horizontal shift left.
- 2 was added to the function, hence, there was a <em>vertical shift up.</em>
