Answer:
Sequence One
Step-by-step explanation:
S = a₁ / (1 − r) is the infinite sum of a geometric series where |r| < 1.
Sequence One: r = 1/5
Sequence Two: r = 2
Sequence Three: not geometric
Sequence Four: r = -3/2
Only Sequence One has |r| < 1.
Answer:
-21 - (-14) = <u>-21</u> + <u>14</u> = <u>-7</u>
Step-by-step explanation:
A - and a - make a +. So -21 - (-14) makes -21 + 14. Solve to get -7.
Hope it helps!
All three sides are the same size
Given that the two lines are parallel, we can assume that the two angles given are supplementary (due to them being same side interior angles)
Supplementary angles - when the sum of their degree measure is 180°
8x - 13 + 4x + 1 = 180
12x = 192
x = 16
