Answer:
=2x²-8x-24 is the answer
Step-by-step explanation:
=(2x+4)(x-6)
opening brackets by multiplying
=2x(x-6)+4(x-6)
=2x²-12x+4x-24
adding like terms
=2x²-8x-24

Answer:
97.6 cm³
Step-by-step explanation:
Volume of plastic object :
Volume of cylinder - volume of cone
From. The diagram. :
Radius, r = diameter /2 = 4/2
Volume of cylinder = pi*r²h
V = 22/7 * 2² * 8 = 100.53096 cm³
Volume of cone = 1/3*pi*r²h
V = 1/3 * 22/7 * 2² * 8
V = 2.9321531 cm³
(100.53096 - 2.9321531) cm³
= 97.598 cm³
= 97.6 cm³
Answer:
6 chores
Step-by-step explanation:
ok so,
4 hours=240minutes
2/3of an hour= 60×2/3
=40 minutes
