Step-by-step explanation:
The value of (f+g)(x) is x^2 + 3x - 11
You can combine this by simply adding the like terms. Start by adding together all of the x^2 terms. Since only g(x) has one of those, we use that in its entirety.
x^2
Next we add together the x terms. f(x) has 7x and g(x) has -4x.
7x + -4x = 3x
Finally, we add together the constants. f(x) has -3 and g(x) has -8.
-3 + -8 = -11
With all of the like terms combined, we simply take the answers and put them together.
x^2 + 3x - 11
Answer:
It was an increase of 200%.
Step-by-step explanation:
In order to identfy the percent of the change we need to first find the absolute value, to do that we subtract the final value from the initial one. We have:
absolute difference = 36 - 12 = 24 inches
Since this value is positive it was an increase. Now we need to find the percentage at which it was increased, to do that we can use a rule of three in a way that the original value is 100% and the value we want to know is the percentage for the absolute increase. We do this as follows:
12 inches -> 100%
24 inches -> x %
12*x = 2400
x = 2400/12 = 200 %
It was an increase of 200%.
