Answer:
21870 km^2
Step-by-step explanation:
Area of sector=1/2r^2(theta)
Where r=18 km and theta=135
Area of sector=1/2(18)^2(135)
=1/2(324)(135)
=1/2(43740)
=21870 km^2
Answer
5
Step-by-step explanation:
141.75 - 68 = 73.75
73.75 / 14.75 = 5
Answer:
21, 24, 29
Step-by-step explanation:
Replace n with 1, 2, and 3, and do the arithmetic.
first term = 1² +20 = 21
second term = 2² +20 = 24
third term = 3² +20 = 29
The first three terms are 21, 24, 29.
Answer:
2m²-6m-8
Step-by-step explanation:
(m-4)(2m+2)
= (m+-4)(2m+2)
= (m)(2m)+(m)(2)+(-4)(2m)+(-4)(2)
= 2m²+2m-8m-8
= 2m²-6m-8
