Answer:
12 x^4 + 18 x^3 - 9 x^2 thus D is the correct answer.
Step-by-step explanation:
Expand the following:
3 x^2 (4 x^2 + 6 x - 3)
3 x^2 (4 x^2 + 6 x - 3) = 3 x^2 (4 x^2) + 3 x^2 (6 x) + 3 x^2 (-3):
3 4 x^2 x^2 + 3 6 x^2 x - 3 3 x^2
3 (-3) = -9:
3 4 x^2 x^2 + 3 6 x^2 x + -9 x^2
3 x^2×6 x = 3 x^(2 + 1)×6:
3 4 x^2 x^2 + 3×6 x^(2 + 1) - 9 x^2
2 + 1 = 3:
3 4 x^2 x^2 + 3 6 x^3 - 9 x^2
3×6 = 18:
3 4 x^2 x^2 + 18 x^3 - 9 x^2
3 x^2×4 x^2 = 3 x^4×4:
3×4 x^4 + 18 x^3 - 9 x^2
3×4 = 12:
Answer: 12 x^4 + 18 x^3 - 9 x^2
Answer: No, No, Yes, Yes, Yes
<u>Step-by-step explanation:</u>
At 2:15 the temperature is 7°
It decreases 3° every 15 minutes ⇒ -3
Here is a table:
time | temperature
2:15 | 7
2:30 | 7 - 3 = 4
2:45 | 7 - 3 - 3 = 1
3:00 | 7 - 3 - 3 - 3 = -2
3:15 | 7 - 3 - 3 - 3 - 3 = -5
3:30 | 7 - 3 - 3 - 3 - 3 - 3 = -8
Do you see a pattern? This can be written as:
7 + (-3) + (-3) + (-3) + (-3) + (-3) + (-3)
7 - (3)(5)
7 + 5(-3)
Answer:
y = -7
Step-by-step explanation:
This is a horizontal line
The y value does not change
It is of the form y=
y = -7
