B
<u>youre incorrect</u>
the actual answer is 864 in²
the formula for area is l x w
or l x w x <em>h</em>
so, you do 9 x 6 x 16
and you get 864 in²
Let the present age of student be x
Present of teacher will be 4x
After 20 years,
Age of student = x + 20
Age of teacher = 4x + 20
According to the given condition after 20 years,
x + 20 = (4x + 20)/2
x + 20 = 2x + 10
2x - x = 20 - 10
x = 10
So student's present age is 10 years while teacher's is 4 x 10 i.e 40 years.
Hope This Helps You!
Answer:
X= 9
Step-by-step explanation:
16x-15 = 30+11x
16x-11x =30+15
5x = 45
x=45/5
x=9
I think that should be it
