Answer:

Step-by-step explanation:
It can be found by integral.
First let's find the intersection points.

Only intersection point is x = 2.
And it is asked to find the area in the interval (2, 4).

We will use integration by parts.


60%
Solve by creating a proportion
27/45 = x/100
Cross multiply to get 2700=45x
Divide 45 on both sides to get x=60
6a+12=2(3a-8)
6a+12=6a-16
-12. -12
6a=6a-4
-6a -6a
0=-4
no solution because the equation is false.
