Answer:
216°
Step-by-step explanation:
The ratio of the sum of smallest and largest to the total of all angles is ...
(9 +15)/(9 +10 +12 +14 +15) = 24/60 = 0.4
__
The total of all angles in an n-gon is 180°(n -2), so the total of all angles in a pentagon is ...
180°(5 -2) = 540°
Then the sum of smallest and largest angles is ...
0.4(540°) = 216°
Answer:
Step-by-step explanation:
You need to distribute 6(s-9) which is now 6s-54 and you got your answer:)
Answer:
w² + 12w + 2
Step-by-step explanation:
( - 2w² + 5w - 4 ) + ( 3w² + 7w + 6 )
= 3w² - 2w² + 5w + 7w + 6 - 4
= 1w² + 12w + 2
= w² + 12w + 2
Answer:
12 m wide
Step-by-step explanation:
12 * 16 =192
Step-by-step explanation:
(a) n² + 3
First term = 1² + 3 = 4
Second term = 2² + 3 = 7
Third term = 3² + 3 = 12
Fourth term = 4² + 3 = 19
10th term = 10² + 3 = 103
(b) 2n²
First term = 2(1)² = 2
Second term = 2(2)² = 8
Third term = 2(3)² = 18
Fourth term = 2(4)²= 32
10th term = 2(10)² = 200
Hence, this is the required solution.
