The garden at João's house was square, with the sides measuring x. It was enlarged as follows: on one side, there was an increase of 6 m and on the other, by 3 m. In this way, the garden started to have a rectangular shape. Knowing that the difference between the new area and the old is 99m2, determine the measure of x.

d

step-by-step explanation:

the answer is two. hope this !

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )

i only know the sequence of arithmetic it adds the first is 5+4 then it goes up as it adds to then it is 9+5 then 14+6 then to 20+7 and so on. 5,9,14,20,27,35.
