Can i have Brainliest?
Answer: No. The answer to this system is y=−85 and y=5, and if you plot that and (3,4) on a graph (I did it on desmos), you will see that it is one square down from the system, meaning it is not a solution to the system. Hope this helps and have a great day!

Answer: 32 sides
Step-by-step explanation:
Formula for interior angle of a polygon = ( n - 2 )180°, where n is the number of sides of the polygon
Now equate the formula to 5400°
( n - 2 ) × 180° = 5400°
open bracket by multiply by 180°
180n° - 360° = 5400°
180n° = 5400° + 360°
180n° = 5760
n = ⁵⁷⁶⁰/₁₈₀
n = 32
so the polygon has 32 sides
