    h = 7a + 4 a = (h-4)/7

    height is four more than 7 times its base so h= 7b+4 where b is base so 7b=h-4 b=(h-4)/7

    \[h= 7b+4 \]\[b= \frac{(h-4)}{7}\]

    Thank you :) Can you help me with two more? Then I'll be done for now. I'm just on a less time because I got up late and I have to work on another project soon. But first I have to get this math out of the way, my teacher makes us have perfectly correct answers

    one leg of a right triangle is 6 millimeters shorter than longer leg, and hypotenuse is 6 millimeters longer than longer leg. Find lengths of sides of triangle.

    Longleg=x shorter leg= x-6 Hypo=x+6 (x+6)^2=(x-6)^2+x^2 x^2+12x+36=x^2-12x+36+x^2 x^2-24x=0 x(x-24)=0 x=0 or x=24
