The area of a rectangle is given by the equation y=x^2-9x+14. if the area is 50 square units, what is the value of x?

50 = x^2 - 9x + 14
x^2 - 9x + 14 - 50 = 0
x^2 - 9x - 36 = 0
(x - 12)(x + 3) = 0

x - 12 = 0
x = 12 <==

x + 3 = 0
x = -3not this one

since the value for "x" cannot be negative, because is a length unit, so is not -3.

0=6x+2y+10 is equivalent to the simplified form: y= -3x - 5• parallel lines always have the same slope, different y intercept knowing this, we can say the slope, or m of the line parallel to y= -3x - 5 is -3.m= -3 hope this could !
