Answer:
108 - 30x - 116x² - 18x³
Step-by-step explanation:
We have to get the value of - (2x + 12) (9x² + 4x - 9)
Now, using the distributive property of multiplication we get
- (2x + 12) (9x² + 4x - 9)
= -[2x (9x² + 4x - 9) + 12 (9x² + 4x - 9)]
= -[(18x³ + 8x² - 18x) + (108x² + 48x - 108)]
= -[18x³ + 116x² + 30x - 108]
= 108 - 30x - 116x² - 18x³ (Answer)

Answer:
53
Step-by-step explanation:
Answer:
9.4m is the answer.
Step-by-step explanation:
a = 8m
b = 5m
c = ?
According to the Pythagoras theorem,
a² + b² = c²
8² + 5² = c²
64 + 25 = c²
89 = c²
c = 9.433
Rounding off,
c = 9.4m
