I actually forgot what a trapezoid was and had to look it up.
Anyway, in an isosceles trapezoid the two legs are the same length, so we now have 3x-9=7x-10. Now it's simply a problem where you solve for x.
3x-9=7x-10
-9=4x-10
1=4x
x=1/4
Hope this helps :)

What is the expression in factored form?x^2+13x+14

nydimaria [60]

Answer:

$\left(x-\dfrac{-13+\sqrt{113}}{2}\right)\left(x-\dfrac{-13-\sqrt{113}}{2}\right).$

Step-by-step explanation:

To factor the expression $x^2+13x+14$ you need to know its roots.

First find the discriminant of this quadratic polynomial:

$D=13^2-4\cdot 1\cdot 14=169-56=113.$

Then the roots of the expression $x^2+13x+14$ are

$x_{1,2}=\dfrac{-13\pm \sqrt{113}}{2}.$

Now the factored form is

$\left(x-\dfrac{-13+\sqrt{113}}{2}\right)\left(x-\dfrac{-13-\sqrt{113}}{2}\right).$

What is 4^6 . 4^6 please help

KonstantinChe [14]

Answer:

4^12 or 16777216

Step-by-step explanation:

4^6* 4^6

We can symplify 4^6* 4^6

Since they both have the same base, we can add there exponent:

4^6* 4^6= 4^12

4^12 equals to 16777216
