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
210 days* (1 week/ 7 days)* (50 inches/ 100 weeks)= 15 inches.
(Note that the units cancel out so you get the answer)
Final answer: 15 inches~
6 cans of paint for a total of 90 dollars spent
I multiplied 120 by .20 to get 24 and subtracted it from 120 to get the amount that still has to be painted which is 96.
96 divided by 16 is 6 which is the number of cans of paint needed to paint the rest. Then just multiply by the cost (15$) and the answer is 90$
4 + 3x = 12
3x = 12 - 4
3x = 8
x = 8/3
x = 2,6 grams
Answer: Option 'B' and 'C' are correct.
Step-by-step explanation:
Since we have given that
A rocket was fired into the air.
The rocket reached a maximum height of 59 feet at point (3.5,59) as shown in the figure.
And it took the rocket 3.5 seconds to reach its maximum height.
and the rocket landed after 6.9 seconds, So option 'D' is false which states The rocket landed after 34 seconds.
The equation that represents the rocket’s height over time has two solutions is completely false as it has only one solutions.
Hence, Option 'B' and 'C' are correct.
