what if d maths is done like dx? L=km/h When L=40,m=175,h=286, (skipping the units) 40=k(175)/ 286 K=286(40)/175=2288/35 L=2288/35=250/50 L=114400/8750 L =13.1m

7/x+5/3x=2/x5 so lcm=3x(x5) 21(x5)+5(x5)=5x 21x105+5x25=5x 26x130=5x 26x to both sides 130=21x divide each side by 21 130/21 x=6.19 is this correct thanks for checking my work. 
Dot product
I cant get the correct answer and I can't figure out what I am doing wrong. If a=(2,2k) and b=(4,k) are perpendicular, find k. I have worked it out, and I got 2 but it doesn't work when I check it in the original equation. It
