The highest pre-tax price I can pay =x
I suggest this equation:
x+(8/100)x=120
least common multiple=100
100x+8x=12000
108x=12000
x=12000/108
x=111.11111...≈111.11$
The highest pre-tax price that i can pay without going over budget is $111.11
15,56^2=x^2+x^2
242,1136=2x^2
x^2= 242,1136:2=121, 0568
x≈11,003
36x^2+60x+25=(12x+5)(3x+5)
The correct answer is "Draw a straight line from D to M". In order to draw a perpendicular line to line KDE you need to create two acrs that intersect above or below KDE. This is illustrated by the point M. This is the point that will create a perpendicular line and intersect KDE at a 90 degree angle.
