Figure A is a scale image of figure B

What is the value of X

x = 5.4

Step-by-step explanation:

Since A is the scale image of B,

4/3 = 7.2/x

Cross multiplying,

4x = 3*7.2

Dividing by4,

x = 3*7.2 / 4

x = 5.4

the first one, all those points on the line just make a strait line.

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
