If the angles are congruent then m∠ACB is 50°.
4x+4=6x-14
-4 -4
4= 2x-14
+14 +14
18=2x
x=9
Plug into one of the expressions.
4(9)+4
46+4
50
Sadly I do not know the scale factor rule yet. Just one lesson ahead :(
I hope I helped on first!

Answer:
Phil Swift here from flex tape
Step-by-step explanation:
Firstly, the best thing to do is to expand the bracket.
To expand, you multiply everything at the front of the bracket by everything inside of the bracket.
4(s+2) becomes 4s (4*s) = 8 (4*2)
Then put this back into the equation, and this becomes;
4s+8+s-1
Then collect the like terms (these are the similar ones)
4s+s becomes 5s
8-1 becomes 7.
Therefore, the simplified equation is 5s+7
Hope this helps :)
