Step-by-step explanation:
the area of the square is (x+2)^2 and the factored form of it is x^2+4x+4
since we know the area is = 7 therefore
x^2 + 4x +4 = 7 and x^2 + 4x = 3
if you want to find the value of x :
x^2+4x+4 = 7
x^2+4x -3 = 0
(x-3)(x-1)=0
x = 3 or
x = 1

1,561/8=188.375
Median
159,164,173, 180,190 ,193,210,238
180+190=370/2=185
Mode-no number repeats itself more than once, therefore there is no mode for this data.
