The answer is:
4x^2+19x+12
1. 4x X x =4x^2
2. 4x X 4=16x
3. 3 X x= 3x
4. 3 X 4= 12
5. 4x^2 + 16x + 3x + 12 = 4x^2+19x+12
By my calculations id say its 0.5 m/s^2.
Answer:
49
Step-by-step explanation:
multiply them by 7
21 = w —28
w = 28 + 21
w = 49
Answer:

Step-by-step explanation:
The chain rule helps us to differentiate functions and a composition of two functions.
Let r(u) and s(u) be two function. Then, composition of these two functions can be be differentiated with the help of chain rule. It states that:

Now, we are given

Then, by chain rule, we have:

Answer:
i think 5x^2-5
Step-by-step explanation:
(3X)(2X-2)
