Answer:
I want to help but I am bad at these questions
Step-by-step explanation:
this is why I gave u no answer
We know that
The sum of exterior angles of any polygon is 360 degrees.
Each exterior angle of a regular polygon = 360/n
where n is the number of sides.
<span>So
n = 360/20 = 18
</span>
the answer is the option
<span>b.18 </span>
Answer & Step-by-step explanation:
4(8 - 6)52 - 6 ÷ (-3)
First, subtract 6 from 8
4(2)52 - 6 ÷ (-3)
4(2)(52) - 6 ÷ (-3)
Multiply 2 by 52
416 - 6 ÷ (-3)
Divide -6 by -3.
416 + 2
Add 2 to 416
418
So, your evaluated answer would be 418.
S10 = -150;
<span> the sum of next 10 terms = S20 - S10 => -550 = S20 + 150 => S20 = -700;
</span>S10 = -150 => 2a1 + 9r = -30;
S20 = -700 => 2a1 + 19r = -70;
Then 10r = -40 => r = -4 , and, 2a1 -36 = -30 => 2a1 = 6 => a1 = 3;
F(x) = 2x + 1
f(3) = 2(3) + 1 = 6 + 1 = 7
g(x) = 3x + 2
g(2) = 3(2) + 2 = 6 + 2 = 8
f(3) ÷ g(2) = ⅞
