Best of Luck!
2x+2y=4x+6y
and then x will equal 2y
Answer:
Yes they are
Step-by-step explanation:
Substitute 2 in for x, and 7 in for y
7= 3(2)+1
7=6+1
7=7
since the statement is true, yes they are solutions
The postulate you can use to prove that those triangles are congruent is the SSS. Since BC and AD are congruent (given), AB and DC are congruent (given), and AC and AC are congruent (i forgot which postulate it is, however, it states that the same line is congruent with itself)
hope this helps
