Is the following a sequence? 1, 7, 49, 343, . . .

Yes, it is an geometric sequence cause the common ratio between them is 7. So

1*7=7

7*7=49

49*7=343

343*7=2401

So, if we keep going, we'll find the ratio 7. So, yeah it is an geometric sequence

HOPE THIS HELPS.HAVE A GREAT DAY

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap
