Pls help asap! i will mark brainliest!
IrinaK [193]

Answer:

AB would be 18 or the first choice.

Since BD is the median that means from A to D and from D to C are equal. We set this up as an equation and solve it.

<em>x + 8 = 2x - 17</em>

<em>   </em><em><u>+ 17       +17</u></em>

<em>x + 25 = 2x</em>

<em><u>-x            -x</u></em>

<em>     25 = x</em>

This gives us our first bit of the answer. Then we plug this into our equation for the length of AB to get 18.

Step-by-step explanation:

hope this helps. . . <3

good luck!      uωu

4.5/w = 3 <br><br>what is the W?​
Oduvanchick [21]

Answer:

w=1.5 or w=13.5

Step-by-step explanation:

this is one answer:

multiply w on both sides to leave u with

4.5=3w

divide both sides by 3

\frac{4.5}{3}=\frac{3w}{3}

1.5=w

_____________________

this is the second one if the first one is wrong:

multiply 4.5 on both sides so that the 4.5/w would leave u with just only w alone.

then 3*4.5=13.5

w=13.5

hope dis helps if not then im not dat smart enough ;?
