1. 18x+16 in

To find the perimeter of a rectangle you have to add all the side together. Two sides are 5x+2 in and two sides are 4x+6 in. 5x+2+5x+2+4x+6+4x+6=18x+16

Sorry I don't know how to do the others.

no i do not : ( what is it?

“a term can be a signed number, a variable, or a constant multiplied by a + sign or j sign. in , the terms are 5x , 3y and 8. when a term is made up of a constant multiplied by a variable or variables, that constant is called a coefficient.” i hope this you.
