Answer:
72cm^2
Step-by-step explanation:
Think of the whole figure as 3 rectangles. Your first one has an area of 8cm*3cm=24cm^2, your second one has an area of (12cm-3cm-3cm)*(8cm-4cm)=6cm*4cm=24cm^2, and your third one has an area of 8cm*3cm=24cm^2. Adding all of the areas together, we have 24cm^2+24cm^2+24cm^2=72cm^2 as the total area of the figure.
Answer:
an= n * (n+1)
Step-by-step explanation:
2,6,12,20,.....
6-2 =4
12-6 = 6
So there is no common difference because these numbers are not the same
It cannot be an arithmetic difference
6/2 =3
12/6 =2
So there is no common ratio because these numbers are not the same
It cannot be geometric
2, 6, 12, 20,...
+4 +6 +8 +10
a1 =2
a2 =2*3
a3 = 2*6=2*2*3=3*4
a4=2*10=2*2*5=4*5
.....
a5 = 5*6 = 30
an= n * (n+1)
