Answer:−21x−8
Step-by-step explanation: All sides have the same measure in a square, therefore all sides are 3x-8. Area is equal to 3x-8 times 3x-8 which is −21x−8
5.5in x 5.2in = 28.6 inches
Answer:
x=23°
Step-by-step explanation:
93°+(3x+18)°=180°
93°+3x+18°=180°
111°+3x=180°
3x=180°-111°
3x=69°
x=69°:3
x=23°
