Answer: X=2
2x plus 2x plus 3x equals 7x and then you add the +5 which means you now have 7x+5=6x+7 which you then solve from there by subtracting the 6x from the left side. You then get x+5=7 meaning x=2.
Since you can directly sum two fractions with the same denominator, we can rearrange the sum as follows:
Now we can sum the first two fraction easily:
We can simplify the first fraction: 12/16=3/4. So, we can sum the two fractions again because they have the same denominator:

Answer:
(e) f′(x)=2xg(x)+x²g′(x)
Step-by-step explanation:
The product rule applies.
(uv)' = u'v +uv'
__
Here, we have u=x² and v=g(x). Then u'=2x and v'=g'(x).
f(x) = x²·g(x)
f'(x) = 2x·g(x) +x²·g'(x)
