Write the quadratic equation whose roots are -4 and -1 and whose leading coefficient is 2

Below

Step-by-step explanation:

here is the factored form of a quadratic equation :

     f(x) = a ( x +/- n ) ( x +/- n )

We can just plug in what we know into this form :

     f(x) = 2 ( x + 4 )( x + 1 )

If you were to plug this into desmos it will show you the graph!

Hope this helps!

i believe the answer is the polygon, heptagon.

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
