Answer:

- 0.8 = - 0.8

n = - 2 is a solution.

Step-by-step explanation:

1.4n + 2 = 2n + 3.2

1.4(- 2) + 2 = 2(- 2) + 3.2

- 2.8 + 2 = - 4 + 3.2

- 0.8 = - 0.8

How to solve

1.4n + 2 = 2n + 3.2

1.4n + 2 - 2 = 2n + 3.2 - 2

1.4n = 2n + 1.2

1.4n - 2n = 2n - 2n + 1.2

- 0.6n = 1.2

- 0.6n ÷ - 0.6 = 1.2 ÷ - 0.6

n = - 2

What's the perimeter or how do you find it?
ziro4ka [17]

The perimeter of inside of the track is 536.44m

<h3>Perimeter of a circle and rectangle</h3>

The perimeter of a circle is also known as the circumference of the circle. The formula for calculating the circumference is expressed as:

C = 2πr

where

r is the radius

From the given diagram

r = 46/2 = 23m

C = 2(3.14)(23)
C = 144.44m

Find the perimeter of the rectangle

P = 2(l+w)

p = 2(46+150)
P = 2(196)
P =392m

The perimeter of the inside track = 144.44 + 392

The perimeter of the inside track = 536.44m

Hence the perimeter of inside of the track is 536.44m
