14m = 400.40
14m ÷14 = 400.40 ÷ 14
m = 28.60
Answer:
A. x=3
Step-by-step explanation:
4(5x+3)=14x+30
multiply 4 to 5x and multiply 4 yo 3
20x+12=14x+30
move terms
20x-14x=30-12
subtract 20x to 14x and subtract 30 to 12
6x=18
divide both sides by 8
x=3
First, area of large circle(A1)= pie×R^2
=3.14×(3+4)^2=3.14×49=154 sq. cm
area of small circle (A2) pie× r^2
=3.14×3^2=28.27 sq.cm
now
area of shaded region= (A1-A2)/3
=(154-28.27)/3
=125.73/3
=41.91 sq. cm
It is a function. None of the x values repeat
Well sure, i don't see why not.
