Hi,
A is an arithmetic sequence
U(n)=U(n-1)+3
The area of a circle is pi times the radius squared (A = π r²). Example of calculating the area of a circle is in the image below.
First distribute the 2(2+4x)
3x-4+4+8x
then just combine like terms.
8+11x
therefore
3x-4+2(2+4x)=8+11x<span />

Answer:
225
Step-by-step explanation:
So we know that 20% of the social workers he surveyed was 45 people. The easiest way to find all 100% of the social workers is to do 45 x 5 because 20% x 5 = 100%. So 45 x 5 = 225.
Hope this helped! :)
