Answer:

1.3

Step-by-step explanation:

BC is the distance between B and C.

BC = x − (-0.4)

BC = x + 0.4

AB is the distance between A and B.

AB = -0.4 − (-1.25)

AB = -0.4 + 1.25

AB = 0.85

Substitute into the equation.

BC = 2AB

x + 0.4 = 2(0.85)

x + 0.4 = 1.7

x = 1.3

Answer:

x=1.3

Step-by-step explanation:

AB=(-0.4-(-1.25))=1.25-0.40=0.85

BC=2AB=2×0.85=1.70

x=-0.4+1.7=1.3
