Step-by-step explanation:
We have two triangles and three rectangles.
The formula of an area of a triangle:
b - base
h - height
The formula of an area of a rectangle:
l - length
w - width
TRIANGLE:
b = 11 in, h = 7 in
RECTANGLE 1:
l = 11 in, w = 14 in
RECTANGLE 2:
l = 9 in, w = 14 in
RECTANGLE 3:
l = 8 in, w = 14 in
The Surface Area:
Substitute:
Answer:
= 4n - 2
Step-by-step explanation:
There is a common difference d between consecutive terms in the sequence, that is
6 - 2 = 10 - 6 = 14 - 10 = 18 - 14 = 4
This indicates the sequence is arithmetic with n th term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 2 and d = 4 , thus
= 2 + 4(n - 1) = 2 + 4n - 4 = 4n - 2
