Hello from MrBillDoesMath!
Answer: Perimeter = 17x + 4
Discussion:
(So you are trying to sneak #2 out of me too..... );
Perimeter = sum of lengths of sides. Starting at the bottom of the figure and proceeding counterclockwise.
Perimeter = (3x +2) + (3x+2) + (4x-1) + (4x-1) + (3x + 2) .
Separate and combine x's and constants:
Perimeter = (3x + 3x+4x+4x+3x) + (2 + 2 -1 -1 + 2) =
= 17x + 4
You answer has the wrong constant value ( you wrote 17x + 1. The constant should be 4)
Thank you,
MrB
Answer:
d = 2
Step-by-step explanation:
Generate the first few terms
a₁ = (2 × 1) - 4 = 2 - 4 = -2
a₂ = (2 × 2) - 4 = 4 - 4 = 0
a₃ = (2 × 3) - 4 = 6 - 4 = 2
a₄ = (2 × 4) - 4 = 8 - 4 = 4
d = 0 - (- 2) = 2 - 0 = 4 - 2 = 2
Answer: 60 degree
