Find the area of the unshaded square

I think your diagram had an error because the instruction says that it is a SQUARE frame with sides that are 8 inches long.

Anyways, following the question, the area of the shaded parts should be:
2(8 x 2) + 2(8 - 2 - 2)(2)
= 32 + 16
= 48 sq in.

Number nine is f(x)= 40x : ) hoped i ya

Ifound this on google “that means that the graph of a function with direct variation has these features: it is a straight line: because the slope is the ratio y/x = k. it passes through the origin (0,0): because y = kx = k (0) = 0.” i hope this you for what your looking for
