Answer:
A≈576.31
Step-by-step explanation:
surface area = bh + L(s1+s2+s3)
surface area = (13*11) + 13 * (10+11+14.87)
After 6x+48=72, you have to subtract 48 on both sides not add. Your final answer will be x=4. 72-48=24.. 24/6= 4.
Step-by-step explanation:
1. x: (-12, -13) y: (12, 13)
2. x: (4 ,9) y: (-4, -9)
3. x: (-10, 8) y: (10, -8)
I also think its 4 but im not sure
