Answer:

Step-by-step explanation:
We have the expression

and we must factor it
Note that the expression has no independent term
Then we can factor the expression by taking the variable 4x as a common factor


Finally the factored form of
is 
Answer:
8.400.703
is it not already in decimal form?
Step-by-step explanation:
Step-by-step explanation:
Srectangle=21*30=630cm^2
Ssemicircle=(11.5^2*pi)/2=132.25pi/2=66.125cm^2*pi
Sfigure=630cm*2+2*66.125cm^2*pi=630cm^2+pi*132.25pi
if we assume that pi=3.14
Sfigure=630cm^2+415.265cm^2=1045.265cm^2
