Write a quadratic equation given the solutions -4,-6
BigorU [14]

x^{2} +6x+24 is the quadratic equation with the solutions -4 and -6

Given that -4 and -6 are solutions of a quadratic equation and asked to find out the quadratic equation

If "a" and "b" are the roots of the quadratic equation then,

sum of roots = a+b

product of roots = ab

There the required quadratic equation is  x^{2} -(a+b)x+ab

Given that a= -4 and b= -6

sum of roots = a+b = -4 +(-6) = -10

product of roots = ab =( -4 )( -6 ) = 24

There the required quadratic equation is x^{2} +10x+24

Hence, x^{2} +6x+24 is the quadratic equation with the solutions -4 and -6

How do you do this ​
Eduardwww [97]

let's recall that the sum of all interior angles in a triangle is 180°, so then

\bf \stackrel{\measuredangle A}{x}+\stackrel{\measuredangle B}{(x+40)}+\stackrel{\measuredangle C}{30} ~~=~~ 180\implies 2x+70=180 \\\\\\ 2x=110\implies x=\cfrac{110}{2}\implies \stackrel{\measuredangle A}{x} = 55

mina [271]

Answer:

A = 437 mm²

Step-by-step explanation:

The general formula for the area of a triangle:

A = \frac{1}{2}bh, where 'b' is the measure of the base and 'h' is the measure of the height

Given the dimensions of the triangle in the picture:

A = \frac{1}{2}(38)(23) = 437 mm²
