Answer:
3524.4 g
Step-by-step explanation:
- Use formula: Density = Mass/Volume
- Mass= Density * Volume
One field is 25 + 45 + 25 + 45 = 140 feet
Second field is 40 + 60 + 40 + 60 = 200 feet.
Therefore, all together, the two fields are 340 feet in perimeter together
8-3(p-4)= 2p
⇒ 8 -3p -3(-4)= 2p (distributive property)
⇒ 8 -3p+ 12= 2p
⇒ 8+12= 2p+3p
⇒ 20= 5p
⇒ 20/5= p
⇒ 4= p
Final answer: p=4~
