Answer:
7x² - 3x - 4
Step-by-step explanation:
<u>Step 1: Write expression</u>
(6x² - x + 3) + (-2x + x² - 7)
<u>Step 2: Combine like terms (x²)</u>
7x² - x + 3 - 2x - 7
<u>Step 3: Combine like terms (x)</u>
7x² - 3x + 3 - 7
<u>Step 4: Combine like terms (constants)</u>
7x² - 3x - 4

Answer:
< 4, < 10 corresponding
< 2, < 3 same side interior
< 8, < 12 other (opposite exterior)
< 6, < 12 alternate interior
< 1, < 2 other (supplementary)
< 15, < 11 alternate interior
< 8, < 9 same side interior
< 2, < 4 corresponding
Two lines that are stretched into infinity and still never intersect are called co-planar lines and are said to be parallel lines. ... Corresponding angles are congruent if the two lines are parallel. All angles that have the same position with regards to the parallel lines and the transversal are corresponding pairs.
