Which formula can be used to describe the sequence below? -8,-5, -2, 1, 4, ...
an=-8a-1 +3; 24 =-8
ay = 3am-1 -11:24 =-8
O an- 3a 9-11 a--8
an = an-1 +3; ay = -8

Find the value of a. the diagram is not to scale. a quadrilateral is drawn. the upper and lower sides are parallel. the interior angle in the upper left corner is labeled a degrees. the angle in the upper right corner is labeled 113 degrees. the angle in the lower right corner is labeled b degrees. the angle in the lower left corner is labeled 36 degrees. a. 36 b. 144 c. 54 d. 126

8000 + 8800 + 8000 + 8 million + 80 trillion + another a katrillion equals

Lena reflected this figure across the x-axis. she writes the vertices of the image as a'(−2, 8), b'(−5, 6), c'(−8, 8), d'(−4, 2).
