How to find the discriminant of
Sonbull [250]

the discriminant   b^2 - 4ac when the equation is in the form of ax^2 +bx+c=0

13x^2-16x = x^2 -x

we need to get in it the standard form

subtract x^2 from each side

12x^2 -16x = -x

add x to each side

12x^2 -15x = 0

12x^2 -15x -0 =0

a=12 b=-15 c=0

b^2 -4ac

the discriminant = b^2

b^2 = (-15)2 = 225

A triangle has sides that measure 2 units, 5 units, and 5. 39 units. What is the area of a circle with a circumference that equa
asambeis [7]

The circumference of the circle is equal to the perimeter of the triangle, then the area of the circle is 12 square units. Option D is correct.

<h3>What is a circle?</h3>

It is a locus of a point drawn equidistant from the center. The distance from the center to the circumference is called the radius of the circle.

A triangle has sides that measure 2 units, 5 units, and 5.39 units.

The circumference of the circle is equal to the perimeter of the triangle. Then the radius of the circle will be

2 \pi r  =  5 + 2 +5.39\\\\r = 1.97

Then the area of the circle will be

\rm Area \ of \ circle  =  \pi r^2\\\\Area \ of \ circle  =  \pi 1.97^2\\\\Area \ of \ circle  =  12.21 \approx 12

The area of the circle is 12 square units.

More about the circle link is given below.
