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)
By addition of the ratio, 5/8 people are adults
144 * 5/8 = 90
Answer:
912 (AND MAKE SURE YOU ADD YOUR YOUR UNITS!)
Step-by-step explanation:
So both side panels are 10 × 12, and the back glass is 12 × 18.
So we are going to do:
2 × (10 × 12) + 12 × 18
= 240 + 216
= 456
But because of the surface area formula we must multiply this by 2!
456 × 2
= 912
So your answer is 912 and whatever your unit is!
