Answer:
–9(3x³ – 8x + 9)
Step-by-step explanation:
–27x³ + 72x – 81
The above equation can be factorised as follow:
–27x³ = –3 * 3 * 3 * x * x * x
72x = 2 * 2 * 2 * 3 * 3 * x
–81 = –3 * 3 * 3 * 3
Common factor = 3 * 3
Greatest common factor = 9
Thus,
–27x³ + 72x – 81 = 9(–3x³ + 8x – 9)
–27x³ + 72x – 81 = –9(3x³ – 8x + 9)
It would have to be number 2) x-3
Add every decimal, then divide by 14 (two weeks, 7 days, total of 14 values), and the closest you get is 0.42.
Volume of the large pyramid = 1/3*(10)² *30= 1000 cm³
Height of the small pyramid that was cut = 30-15=15 cm
Volume of the small pyramid = 1/3*(5)²*15=125 cm³
Volume of the frustum = Volume large pyramid - volume small pyramid=
=1000-125=875 cm³
Answer is 875 cm³.
