∑ ( from n = 1 to n =5 ) 3 · ( -2 ) ^( n -1 )
a 1 = 3 · ( -2 ) ^0 = 3
a 2 = 3 · ( - 2 ) = - 6
a 3 = 3 · 4 = 12
a 4 = 3 · ( - 8 ) = - 24
a 5 = 3 · 16 = 48
3 - 6 + 12 - 24 + 48 = 33
Answer: C ) 33
Hey there!
Here is ur answer >>>>
A) 4(X + 1 ) = 5x + 12
4x + 4 = 5x + 12
X = 4 - 12
X = -8
B) 13 ( 6 - x ) - 4 ( 3x + 12 ) = 0
78 - 13x - 12x - 48 = 0
30 - 25x = 0
30 = 25x
X = 30/25
X = 6/5
All of them are solved in these methods
The draw an inscribed polygon inside the circle, the very thing to do is to draw the circle. Thus, the answer is the fourth choice, "Place a point on your paper and then use a compass to construct a circle". After which, we can locate the vertices of the polygon in the circumference of the circle and connect them to make the polygon.
The number is 5. 27-12=15/3=5 is how you get the answer.
