Answer:
x(x+y+3)(x+y-3)
Step-by-step explanation:
x³+2x²y+xy²-9x
= x((x²+2xy+y²)-3²)
= x((x+y)² - 3²)
= x(x+y+3)(x+y-3)
Answer:
14,130 cm³
Step-by-step explanation:
V = 4/3πr³
= 4/3 x 3.14 x 15 x 15 x 15
= 20 x 225 x 3.14
= 706.5 x 20
= 14,130 cm³

Answer:
(a) 0.5km or 500m
(b) 100m
Step-by-step explanation:
(a) 1 hour = 60 minutes
60 minutes = 30km
5 minutes = 30 ÷ 60
= 0.5km = 500m
(b) 1 minute = 500m ÷ 5
= 100m
Answer: A. The molten mixture of rock-forming substances, gases, and water from the mantle
Magma is a mass of molten rock that is found in the deepest layers of the Earth at high temperature and pressure, and that can flow out through a volcano.
The composition of this mass is a mixture of liquids, volatile and solids that when they reach the surface in an eruption becomes lava, which when cooled crystallizes and gives rise to the formation of igneous rocks.
