The answer to the question is 112°
First, you must set up an equation to find x.
Then, you must use distributive property to simplify the parentheses.
Next, add like terms.
Then, subtract 20 on each side.
Next, divide 10 on each side.
Now, you must substitute 34 in for x.
You are trying to isolate the variable (n) so you would subtract 7.4 on both sides. Therefore n=5.3-7.4 which equals -2.1
The derivative here is what you get when you bring the exponent down as the coefficient (i.e. the 3) and subtract the exponent by 1. In this case, the answer will be 3x^2.
Answer:
% Change = (87.5 - 125) / 125 * 100%
= -37.5 / 125 * 100%
= -0.3 * 100%
= -30 %
The percent change is -30 % or 30% decrease.
