You would divide 198 by 9.
198÷9=22
Each person would clean 22 rooms.
(x^4 - 9)(x^3 + 9)
This is a binomial * binomial. Use the FOIL method for multiplying.
First, outer, inner, last.
x^4 * x^3 = x^7
x°^4 * 9 = 9x^4
-9 * x^3 = -9 x^3
-9 * 9 = -81
Putting it back together.
x^7 +9x^4 -9x^3 - 81

Answer : -2.7d+3.2h-18
Please leave a thanks <3
Answer:
Step-by-step explanation:
Volume = 1800 cm^3
The volume formula is V = L*w * h
The length = 12
The width = 10
The height = x
12*10*x = 1800
120 * x = 1800
x = 1800/120
x = 15
The rock is 15 cm high.
