\[EF=\frac{ AB+DC }{ 2 }\]\[14x=\frac{ 12x+18x-20 }{ 2 }\]

OpenStudy (anonymous):

\[14x=\frac{ 30x-20 }{ 2 }\]Can you solve from here? :o)

OpenStudy (ammarah):

.625?

OpenStudy (anonymous):

Well, you can divide the right by the 2: \[14x=15x-10\]\[14x-15x=-10\]\[-1x=-10\]\[x=10\]

OpenStudy (ammarah):

could u do the problem above this one?

OpenStudy (anonymous):

Notice (0, 0) goes to (2, 3). Therefore, you go over 2 and up 3 to find that last point. :o)

OpenStudy (anonymous):

For #25: \[d=\sqrt{(x2-x1)^2+(y2-y1)^2}\]\[d=\sqrt{(3+2)^2+(4+3)^2}\]

OpenStudy (ammarah):
