Answer:
Step-by-step explanation:
the first figure is rectangle , so
length = 15cm, breadth = 6cm
therefore area = l * b = 15*6 = 90cm^2
second figure is also a rectangle so,
length = 12+6 =18 cm ( or 9+9) , breadth = 9cm
therefore area = l*b =18*9 = 162cm^2
third figure is a semicircle , so
d = 11+9 = 20 cm , r = d/2 =20/2 =10cm
area of semicircle = *
=1/2*22/7 *10*10
=1100/7 = 157 1/7 cm^2
if you add all the areas then you will get the requires area

Answer:
Option C
Step-by-step explanation:
<u><em>Verify each expression</em></u>
case A) we have
In this expression the term of n is 6n
so
has a coefficient of positive 6
case B) we have
In this expression the term of n is -5n
so
has a coefficient of negative 5
case C) we have
In this expression the term of n is n
so
has a coefficient of positive 1
case D) we have
In this expression the term of n is -n
so
has a coefficient of negative 1
