Answer:
2 irrational solutions.
Step-by-step explanation:
6p^2 = 8p + 3
0 = -6p^2 + 8p + 3
The roots are:
p = (2/3) - (8.5)^(1/2)/3, and
p = (2/3) + (8.5)^(1/2)/3
These are irrational numbers.
There are 2 irrational solutions.

the answer is f(a)=2a²+ 4a+5
Question 7
2a²+4ah+2h²+4a+4h+5
Answer: 245 feet
Step-by-step explanation:
Given: The height of the rocket after t seconds is represented by the formula:
[Differentiate both sides w.r.t. t]
Put
Also, 
i.e. height is maximum at t=7.
Maximum height = 
Hence, the maximum height the rocket reaches = 245 feet.
