So 8x+4+4x+8=15x-9
Combine like terms.
12x+12=15x-9
Add 9 to both sides.
12x+21=15x
Subtract 12 from both sides.
21=3x
Divide both sides by 3.
x=7
Now plug in 7 for x in 8x+4.
8(7)+4
56+4
=60
Answer:
Yes.
Step-by-step explanation:
Yes they are because that is the definition of congruency.
8 because it goes from 1s 10s 100s so 8 is the answer
I think the answer is 3 but I’m not sure.
Hope this helps!
