Step-by-step explanation:

Area  \: of  \: parallelogram  \\  =  {x}^{2}  + 9x - 36 \\  =  {x}^{2}  + 12x - 3x - 36 \\  = x(x + 12) - 3(x + 12) \\  = (x  + 12)(x - 3) \\  \implies \\ length = (x + 12) \: units \\ width = (x - 3) \: units \\

For this parallelogram to exist least value of x should be 4.

Because if x = 3

(x - 3)= 3 - 3 =0

Thus width of parallelogram would become zero as a result area of parallelogram would become zero i. e. Parallelogram won't exist.

If A and B are two points having coordinates (- 2, 2) and (2,-4) respectively, find the coordinates of P such that AP= AB.​
Karo-lina-s [1.5K]

Answer:

(0,1)

Step-by-step explanation:

The mid point of A(-2,2) and B(2,-4) is the coordinates of point P, which is (x,y)

Hence, the line AB = AP + PB.

At point AP: x = (-2+2)/2 = 0

also, point PB: y = (2 - 4)/2 = -1

Therefore, coordinates of point P = (0,-1)
