<em>Identify</em>
3 + 8x - 2y - x + 1 + 4y
<u>Step 2: Simplify</u>
- Combine like terms (x): 7x + 3 - 2y + 1 + 4y
- Combine like terms (y): 7x + 2y + 3 + 1
- Combine like terms: 7x + 2y + 4
5-(-4)
5 + 4 = 9
exceeds by 9
If AB is parallel to CD, then A’B’ is parallel to C’D’.
The missing reason to complete Hector's proof is
<span>Corresponding Parts of Congruent Triangles Are Congruent
It's been established in the previous statement that triangle LNO and triangle PNM are congruent by the AAS Postulate.
The proof
</span>Corresponding Parts of Congruent Triangles Are Congruent
is comprehensive.
