4x - 9 = 143
4x = 152
x = 38
Answer: -12 but could be wrong
Step-by-step explanation:
I don't know that format but I'm going to take a guess.
x^2 +2x - 8 -(2x+8) then plug in x=2
x^2 + 2x - 8 - 2x - 8
x^2 -16
= 2^2 - 16 = -12
The total area is given by:
A1 = (300) * (500)
A1 = 150000 feet ^ 2
The area occupied by 5 people is:
A2 = (5) * (5)
A2 = 25 feet ^ 2
Then, we can make the following rule of three:
5 --------> 25
x --------> 150000
Clearing x we have:
x = (150000/25) * (5)
x = 30000
Answer:
D. 30,000 people
The answer is 1.
8x6=48
8x5 + 8x1 = 48
