7-188.

Suppose you want to multiply a 5-by-11 matrix by a

*c*-by-*d*matrix. Homework Help ✎For what value of

*c*will the multiplication be defined?Given this value of

*c*, what will be the dimensions of the product matrix?

The multiplication will only be defined if *c* = 11.

The product matrix will be a 5-by-*d* matrix.
