Answer:
The height is 11/2
Step-by-step explanation:
We know SA = 30n
and r = 2
We are solving for h. So plug in our values
30n = 2n(2)^2 + 2n(2)h
Multiply and square on the right side terms
30n = 8n + 4nh
Divide everything by n
30 = 8 + 4h
Subtract 8 on both sides
22 = 4h
Divide by 4 on both sides
h = 22/4 = 11/2
Check:
30n = 2n(2)^2 + 2n(2)(11/2)
30n = 8n + 22n
30n = 30n
Answer:
Option (b) is correct.
The solution of the quadratic equation
is -7 and 3
Step-by-step explanation:
Consider the given quadratic equation
This can be rewritten as,
We can solve the quadratic equation using middle term splitting method,
4x can be written as 7x-3x , we get,
Taking terms common, we get,
Thus,
Thus, we get (x-3)= 0 or (x+7)= 0
this gives x = 3 or x = -7
Thus, the solution of the quadratic equation
is -7 and 3
