The figures in the picture are similar to each other find the value of x
alisha [4.7K]

Answer:

x = 7

Step-by-step explanation:

Similar figures have sides that are proportional.  Setting up a proportion for the sides of the figures will help solve for 'x':

\frac{small}{large}=\frac{3}{6}=\frac{(x-3)}{(x+1)}

Cross-multiply:  3(x + 1) = 6(x - 3)

Distribute:  3x + 3 = 6x - 18

Combine like terms:  21 = 3x

Solve for 'x':  x = 7

How to find the discriminant of
Evgen [1.6K]

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
