The answer is two solutions 51 and 5 to the answer
We can determine from their equations whether two lines are parallel by comparing their slopes. If the slopes are the same and the y-intercepts are different, the lines are parallel.
Unlike parallel lines, perpendicular lines do intersect. Their intersection forms a right, or 90-degree, angle.
Answer:
11
Step-by-step explanation:
Evaluate the parenthesis to begin with
2*3 = 2² - 3² = 4 - 9 = - 5
Thus
6 * (- 5) = 6² - (- 5)² = 36 - 25 = 11

Maybe a square that is 4 on every side
