Answer:
C. Surveys
Step-by-step explanation:
A primary source of information is the gathering of data that hasn't already been collected.
One of the best ways is to use a market research survey.
A, B, and D are wrong. They are all secondary sources — they provide information that someone else has generated.
X-(26 + 4) =65 the answer is x=95
width = 2n+8
length = 3 * width = 3*(2n+8) = 6n+24
Perimeter = 2(l+w)
= 2( 6n+24 + 2n+8)
= 2( 8n+32)
96 = 16n +64
-64 -64
--------------------------------------
32 = 16n divide by `16
2 = n
width = 2n+8 = 2*n + 8= 4 + 8 = 12
length = 3*width = 3*12 = 36
