Can someone please help me!!

Answer:

<h2>x = 6</h2>

Step-by-step explanation:

Use Angle Bisector theorem (look at the picture).

We have the equation:

\dfrac{3}{x}=\dfrac{x-4}{4}        <em>cross multiply</em>

x(x-4)=(3)(4)          <em>use the distributive property</em>

x^2-4x=12           <em>subtract 12 from both sides</em>

x^2-4x-12=0\\\\x^2+2x-6x-12=0\\\\x(x+2)-6(x+2)=0\\\\(x+2)(x-6)=0\iff x+2=0\ \vee\ x-6=0

x+2=0        <em>subtract 2 from both sides</em>

x=-2

x-6=0       <em>add 6 to both sides</em>

x=6

How many positive 3-digit numbers are divisible by 11?
enyata [817]

Answer:

81

Step-by-step explanation:

If a number is divisible by 11, then you can make those numbers by multiplying 11 by any number. Like 33 is divisible by 11 because 3×11 is 33.

Of course, 33 is too small, we are looking for 3-digit numbers...
