The perimeter of the triangle is 21.4 units

<h3>How to determine the perimeter?</h3>

The points are given as:

A(−2,2), B(5,−3), and C(−4,−1)

Calculate the side lengths using:

d = \sqrt{(x_2 -x_1)^2 + (y_2 -y_1)^2

So, we have:

AB = \sqrt{(-2 -5)^2 + (2 + 3)^2} = 8.6

AC = \sqrt{(-2 +4)^2 + (2 + 1)^2} = 3.6

BC = \sqrt{(5+4)^2 + (-3 + 1)^2} = 9.2

The perimeter is then calculated as:

P = AB + AC + BC

This gives

P = 8.6 + 3.6 + 9.2

Evaluate

P = 21.4

Hence, the perimeter of the triangle is 21.4 units

27x + 24y= 4.5<br><br> 1.5x + y =0.225
Goryan [66]

Answer:

x = 0.1, y = 0.075

Step-by-step explanation:

Given the 2 equations

27x + 24y = 4.5 → (1)

1.5x + y = 0.225 → (2)

Multiplying (2) by - 24 and adding to (1) will eliminate the y- term

- 36x - 24y = - 5.4 → (3)

Add (1) and (3) term by term to eliminate y

- 9x = - 0.9 ( divide both sides by - 9 )

x = 0.1

Substitute x = 0.1 into either of the 2 equations and solve for y

Substituting into (2)

1.5(0.1) + y = 0.225

0.15 + y = 0.225 ( subtract 0.15 from both sides )

y = 0.075
