Step 1 it says Additive inverse, that is not additive inverse. Additive inverse is the opposite of a number. There is no opposite number in the problem. And step 5 is the answer, it shouldn't be simplify. Hope that helps! <span />
Answer:
15 inches
Step-by-step explanation:
The formula for the area of the area of a triangle is bxh/2.
The base is 6 inches, and the height is 5 inches. 6x5=30. 30/2=15.
Would appreciate if you marked my answer as brainliest, have a good day :)
Answer:
I think it would have to be C because 20-13=7
I believe it would be a 100 correct me if I’m wrong since every one box equals 20 books 5 boxes would contain 100.
Step-by-step explanation:
The particle is at rest when the derivative of x(t), which is its velocity, is zero, i.e.,
![\dfrac{d}{dt}[x(t)] = \dot{x}(t) = 0](https://tex.z-dn.net/?f=%5Cdfrac%7Bd%7D%7Bdt%7D%5Bx%28t%29%5D%20%3D%20%5Cdot%7Bx%7D%28t%29%20%3D%200)
Since 
its derivative is
Equating this to zero, we get
This is a familiar quadratic equation whose roots are
This means that the particle will be at rest at t = 3 and t= 4.
