Find the value of x. Give the answer in simplest radical form.

Vilka [71]

Answer:

X = 8√2.

Step-by-step explanation:

In a 45-45-90 triangle the ratio of the sides are x:x:√2 x.

So here, x = 8 and the side X = 8√2.

X is equal to 23

15/3 = 5

36/3 = 12

39/3 = 13 then add the 10 and you get 23

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

Delvig [45]

Answer:

Step-by-step explanation:

if the roots are 3 and -6, we can start with:

$(x-3)(x+6)=0$

But the leading coefficient must be 3, we just add a 3 to one of the x's:

$( 3 x-3)(x+6)=0$

But now we have to make sure the roots work again:

$( 3 x-9)(x+6)=0$

So our equation is:
