Answer:
Question it in english
Step-by-step explanation:
Answer:
63
Step-by-step explanation:
let the two numbers be x,y (x>y)
Then x+y = 16 and x-y = 2
We know that (x+y)^2 - (x-y)^2 = 4xy
So 4xy = 16^2 - 2^2 => 4xy = (16+2)(16–2)
So xy = 18×14/4 = 63
Product of the numbers = 63
The lines are perpendicular.

35 hectometers
Step-by-step explanation:
1 kilometer=10 hectometers
3 1/2=7/2
7/2*10=35
Answer:
He confused the height and the diameter
Step-by-step explanation:
the formula should have looked like this
V= 3.14 (2.5)^2 (24)
the reason why it is 2.5 and not 5 is because 5 is the diameter so divide 5 by 2 and you get 2.5
V= 3.14 (6.25) (24)
V= 3.14 (150)
V= 471
