If its a proportion then

\\ \sf\longmapsto 42-m=m-18

\\ \sf\longmapsto 42+18=m+m

\\ \sf\longmapsto 2m=60

\\ \sf\longmapsto m=\dfrac{60}{2}

\\ \sf\longmapsto m=30

Quadratic 6X2 + 5X = -7
poizon [28]
Ok, so here your being asked to solve 6x2<span> + 5x = -7 

The procedure that I did was using this formula it led me to get the following:
</span>Using the formula:

x = -(-5) ± √(-5)² - 4(6)(-6)/ 2(6)
x = 5 ± √ 25 + 144 / 12
x = 5 ± √ 169 / 12
x = 5 ± 13/12

x1 = 5 + 13/12
x1 = 18/12
x1 = 3/2

x2 = 5 - 13/12
x2 = -8/12
<span> x2 = - 2/3 

Hope this helped :)</span>
