How do I prove statement 3? with a reason

In triangle DEF and triangle DGF

DE=DG ( given)

EF=GF ( given)

DF=DF ( common)

therefore triangle DEF is congruent to triangle DGF

hope it help u dear..

answer: -1

step-by-step explanation:

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

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
