Answer:
C
Step-by-step explanation:
Given
(a + 3)(- 2a² + 15a + 6b²)
Each term in the second factor is multiplied by each term in the first factor, that is
a(- 2a² + 15a + 6b²) + 3(- 2a² + 15a + 6b²) ← distribute both parenthesis
= - 2a³ + 15a² + 6ab² - 6a² + 45a + 18b² ← collect like terms
= - 2a³ + 9a² + 45a + 6ab² + 18b²
Answer:
Since the question requires you to give the answer in terms of steps/minute, the first step would be to convert hours to minutes:
12.5 hours = 750 minutes
Next, if he took 775 steps in 750 minutes, how many would he take in 1 minute?
This requires you to set up the question as a proportion:
(775 steps/ 750 minutes) = (x steps/1 minute)
(1 * 775)/750 = 31/30 = 1.033
he took ~1 step per minute
If triangle ABC is equilateral, you know that each angle is 60 degrees because 180(the total of all angles in a triangle) divided by 3 is 60. 60 would equal 3x-12. 60=3x-12 then you cancel out the 12, 56=3x, and finally divide by 3... x=18.66! Hope this helps!
(4*4*10)*3
160*3=480
(5*3*10)*2
150*2=300
480+300=780 cub. meters
