Answer:
hi there!
the correct answer to question is: x=-3
Step-by-step explanation:
you move -12x to the other side by adding it on both sides to get: -3x=9 then you divide -3 on both sides to get x=-3
The derivative of x^3 is 3x^2.... is that what you were looking for?
Answer:

Step-by-step explanation:
Consider right triangle ABC with right angle C.
In this triangle,
- BA = 9.8 in
- CB = 6.3 in
- CA = 7.5 in
Write trigonometric functions:

Hence,

→ 
8 and 10 can both be divided by 2. So, 8 ÷ 2 is 4 and 10 ÷ 2 is 5.
Hope this helps :)
I feel like it’s 180 dregrees, good luck!
