Write the quadratic equation whose roots are 6 and 5, and whose leading coefficient is 3

y = 3x^2 - 33x + 90

Step-by-step explanation:

y= 3(x - 6)(x - 5)

if you expand this you get

y = 3(x^2 - 6x - 5x +30)

y = 3(x^2 - 11x + 30) Now use the 3

y = 3x^2 - 33x + 90

And that would be the answer.

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
