Answer:
im not very good at geometry but is there any choices you could pick from
Step-by-step explanation:
Area of <span>trapezoid=(7+3)*h/2=20 cm2
10*h/2=20
5h=20
h=4
the answer is 4.0 cm</span>
In an inverse function, the x-values and y-values switch. So if (a,b) is a point in the f(x) function, then (b,a) is a point in the f^(-1)(x) function.
Switch all x and y-values in the function.
