The perimeter of the right triangle is 12y.
<h3>How to find the sides of a right triangle?</h3>
A right triangle has one of its angles as 90 degrees.
The sides can be found using Pythagoras theorem.
Therefore,
c² = a² + b²
where
- c = hypotenuse
- a and b are the other legs
Therefore,
4y and 3y are the other legs.
5y is the hypotenuse of the triangle
(5y)² = (4y)² + (3y)²
25y² = 16y² + 9y²
The perimeter of the triangle = 4y + 5y + 3y = 12y

To work out what the other side is that you times 12 to get to 24 you would do: 24 divided by 12 equals 2 therefore you would do 12 times 2 to get 24
The equation given above is written here below with all the terms transposed to only one side of the equation.
2x² + 3x + 8 = 0
The quadratic formula used for the determination of the roots is,
x = (-b +/- sqrt (b² - 4ac)) / 2a
In the quadratic equation above, we have the numerical coefficients.
a = 2
b = 3
c = 8
Substituting the known values,
x = (-3 +/- sqrt (3² - 4(2)(8))/ (2)(2)
x = -0.75 + 1.854i and x = -0.75 - 1.854i
By the calculated roots above, it is known that the roots are imaginary.
