Answer:
4762 N/m^2
Step-by-step explanation:
Find area.
30x5.6=168
Convert to m^2
168cm^2=0.0168m^2
Use pressure formula to get answer
P=F/A
P=80/0.0168
P=4762 N/m^2
Answer:
x=3 , x=-3
Step-by-step explanation:

Add 9 on both sides

To remove base 'e' we take ln on both sides


Both sides have ln , so we make the terms equal

Take square root on both sides

x=3 , x=-3
Answer:
13
Step-by-step explanation:
- x × (x + 9) = x² + 9x = 286
- x² + 9x - 286 = 0
- (x - 13)(x + 22)
- x = 13 or -22
- Since you cannot have negative length, it’s 13
