Answer:
The coordinates of B is (4,1)
Step-by-step explanation:
You can use the formula of mid-point. It is given that the midpoint of AB is (4,5). So you have to substitute the coordinates of A into the formula :
Let M be (4,5),
Let (x1,y1) be A(4,9),
Let (x2,y2) be B coordinates,
Then you could solve it :

Area = (base times height) / 2
Can rewrite it as
A= b * h * 1/2
16 = (x^(1/3)) * ( x^(1/2)) * (1/2))
Multiply by 2 to simplify
32 = x^(1/3) * x^(1/2)
32=x ^(5/6)
X=64
Base = 4
Height = 8
Please look below at how you multiply variables that have fractions as exponents (you need to add the exponents, common denominator and all that)
