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

What is the length of the indicated side of the triangle?
anastassius [24]

9514 1404 393

Answer:

  15 m

Step-by-step explanation:

The area of the square attached to the third side is the sum of the areas of the other squares:

  81 m² +144 m² = 225 m²

The side length is the square root of this:

  ? m = √(225 m²) = 15 m

The length of the indicated side is 15 m.

Two sides of a triangle are 8cm and 12cm. Which of the following CANNOT be the measure of the third side,
blondinia [14]

Answer:

4 cannot be the measure of the third side. This is because of the Triangle Inequality Theorem, which states that the sum of two sides of a triangle must be greater than the third side (A+B>C, A+C>B, B+C>A) In this example, if side C were 4, side C (4) plus side A (8) would be 12. Since side B is 12, and 12 cannot be greater than 12, 4 would not work.

Answer=8
