Given δ abc ≅ δ efg, which congruency statement is true? a. ec ≅ bf b. cb ≅ ge c. ba ≅ ef d. ac ≅ eg

Both C. BA ≅ EF and D. AC ≅ EG are correct.

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

b, i believe, but not sure.
