Find the perimeter and area of the figure below.

hichkok12 [17]

Answer:

perimeter = 40

area = 46(unit)^2

Step-by-step explanation:

Perimeter - all sides added together

Find unknown sides (8-3 = 5, 12-2 = 10)
Add all sides together (8+2+5+10+3+12 = 40)

Area - Length multiplied by width

Divide shape into two rectangles (#1 is 2x5 and #2 is 3x12)
Find individual area (rectangle #1: 2*5 = 10 / rectangle #2: 3*12 = 36)
Add areas together (10+36 = 46)
Finish with unit squared (46___^2)

Find a common difference of the arithmetic sequence -2, -1 4/5, -1 3/5, -1 2/5,

elixir [45]

Answer:

The common difference is $\frac{1}{5}$ or 0.2

Step-by-step explanation:

Given:

Arithmetic Sequence -2, -1 4/5, -1 3/5, -1 2/5,

First term = a₁ = -2

Second term = a₂ = $\frac{-9}{5}$

Third term = a₃ = $\frac{-8}{5}$

Fourth term = a₄ = $\frac{-7}{5}$

To Find:

Common Difference = d = ?

Solution:

Formula for Common Difference d , $\textrm{common difference}= \textrm{Second Term} -\textrm{First Term}=\textrm{Third Term}-\textrm{Second Term}$

$\textrm{common difference} = a_{2}- a_{1}= a_{3}- a_{2}=a_{4}- a_{3}$

∴ $d = \frac{-9}{5}-(-2)\\d=\frac{-9}{5}+2\\d=\frac{1}{5}\\ \therefore d =0.2\\$

The common difference is $\frac{1}{5}$ or 0.2
