X=-1 is the answer. Hope that helps!
We know the area of the middle rectangle is 48 (length * width). removing that rectangle leaves us with two semicircles. you can combine those semicircles to be the equivalent of one circle. the area for a circle is r^2 * pi. we know the diameter is 4 because that is where we cut the semicircles. radius is half the diameter, so r is 2. 2^2 is 4, 4* pi is 12.56. add 12.56 (area of semicircles) with 48 (area of rectangle) and we get 60.56

Step-by-step explanation:
Answer:
x=7; NL=12; NP+20
Step-by-step explanation:
In order to make b the subject of this equation, we must isolate it on the left side. We can do this by following these steps:

Subtract b from both sides


Subtract P from both sides


Now, we have isolated b, but it is negative. We can fix this by multiplying both sides of the equation by -1.


Which is your final answer.
