Which inequality represents all possible solutions of -21b< 3

The inequality that represents all possible solutions of -21b<3 is                 b > -(3/21).

Step-by-step explanation:

Given -21b < 3 ⇒ b > 3/-21 ⇒ b > -(3/21)

When you pass a negative term from one side of the inequation to the other side, the relationship between the terms (< or >, etc) have to change, it means if the sign was > you have to change it to <, and so on.

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
