This is a square. because the lengths and the widths are equal. I mean, all four sides are equal.
the area of a square is the square of a side
and the perimeter of a square is a side multiplied by 4
hope this helps
good luck
Answer:
Step-by-step explanation:
Diameter = 10 * 2 = 20in
Diameter of inscribed circle = Length of one side of square
Perimeter of square = 4 * length
P = 4 * 20 = 80in
Answer:
a_n = 3 + a_n − 1 a_ n = 3 + a_ n − 1
Step-by-step explanation:
The first term is 8, so a_1 = 8
Each time we want a new term, we add on 3
8+3 = 11
11+3 = 14
14+3 = 17
17+3 = 20
23+3 = 26
and so on
This recursive step of adding on 3 to the prior term is written as this: an = 3+a_n-1 which says "to get the nth term, add 3 to the term just before the nth term"
It should be 8 until as well
