Step-by-step explanation:
9x2+5x4
= 18 + 20
= 38
the answer is 38
Answer:

Step-by-step explanation:
Given that the the difference of cubes is
a³ - b³ = (a - b)(a² + ab + b²)
Given
64
- 27 ← a difference of cubes
with a = 4x² and b = 3, thus
= (4x²)³ - 3³
= (4x² - 3)(16
+ 12x² + 9) ← in factored form
When it hits the ground h = 0 so we have
-16t^2 + 36t + 4 = 0
t = 2.36 seconds to nearest hundredth.
