Answer:
- 2t³ + 4t² - t
Step-by-step explanation:
f(t) - g(t)
= 3t³ - 4t + 6t² - (5t³ + 2t² - 3t) ← distribute parenthesis by - 1
= 3t³ - 4t + 6t² - 5t³ - 2t² + 3t ← collect like terms
= - 2t³ + 4t² - t
The answer is 3 blocks per minute, because 30 divided 10 = 3.
Answer:

Weird question xD
You have to use the Pythagorean theorem on this one.
a^2 + b^2 = c^2
11^2 + h^2 = 12^2
121 + h^2 = 144
h^2 = 23
h = 4.79583
