Adina has a rectangular garden that measures 9 m wide by 13 m long. she wants to increase the area to 192 m² by increasing the width and length by the same amount.

what will be the length (longer dimension) of the new garden?

A=LW and we wish to increase L and W by the same amount to get an area of 192m^2.

(9+2x)(13+2x)=192

117+18x+26x+4x^2=192

4x^2+44x+117=192

4x^2+44x=75

x^2+11x=18.75

(x+5.5)^2=30.25+18.75 

(x+5.5)^2=49

x+5.5=±7

x=-5.5±7, since x>0

x=1.5

13+2(1.5)

16 meters will be the new longer dimension.

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 !
