I'm assuming the equation is (2 * r) * (t - 3)... then you will just need to substitute the answers into the equation:
(2 * 2) * (6 - 3) = 4 * 3 = 12

Answer:
Second term=9
Third term=14
Twelfth term=59
Eightieth term=399
nth term=-1+5n
Step-by-step explanation:
First term=a=4
Common difference=d=5
using the formula
Tn=a + d x (n-1)
Second term=4 + 5 x (2-1)
Second term=4 + 5 x 1
Second term=4 + 5
Second term=9
3rd term=4+5x(3-1)
3rd term=4+5x2
3rd term=4+10
3rd term=14
12th term=4+5x(12-1)
12th term=4+5x11
12th term=4+55
12th term=59
80th term=4+5x(80-1)
80th term=4+5x79
80th term=4+395
80th term=399
nth term=4+5(n-1)
nth term=4+5n-5
nth term=4-5+5n
nth term=-1+5n
Answer:
52 cm^2
Step-by-step explanation:
1) find the area of the rectangle
A = base x width = 8 x 5 = 40 cm^2
2) find the area of the triangle
A = (base x height)/2 = (8x3)/2 = 12 cm^2
3) find the total area
A = 40 + 12 = 52 cm^2
