What is the value of x?

x = 12

Step-by-step explanation:

From the similar figures given in the picture,

(Figure A ~ Figure B)

Corresponding sides of the figures will be proportional.

By this property of the similarity,

x =

x = 12

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
