Answer:
B. x=6
move all terms to the left that don't contain x to the right side and solve.
Negative 34 means (-34)
times means to multiply, then

To do it without a calculator we will make -34
-30 + -4, then multiply -30 by 1567 and multiply -4 by 1567 then add the two answers


Then add the answers

The answer is -53278
Answer:
the fourth answer
Step-by-step explanation:
When an spherical balloon volume is increasing at the rate of
then the diameter of the balloon is increasing 
How can we find the rate of change of balloon's diameter ?
The volume of a spherical balloon is 
In form of diameter we can write as

Now we will differentiate both sides wrt to
we get

Given in the question 
thus when we substitute the values we get
