Answer:
5n-10 < 6n-8
n - is the variable that's stands for the unspecified number
step 1. ten is less than 5 times a number
step 2. LESS THAN SIGN :)
step 3. six times the number decreased by 8
......................
oh and if you're looking to simplify that problem I believe it would be worked out like this....5n-10<6n-8....subtract 5 from both sides....-10
The wall has a shape of trapezium, the area will therefore be given by:
A=1/2(a+b)*h
where a and b are the side length, h is height:
a=25, b=15, h=40
thus the area of the wall will be:
A=1/2(25+15)×40
A=1/2×40×40
A=800 ft²
Answer: Area=800 ft²
