Write two expressions to represent and solve each problem. Then solve the problem. PLZ HELP...BRAINLIEST

I'm not sure this counts as 2 expressions, but 1. 5*4-3*4=w or 2. (5-3)*4=w

You will have 8ft of wood left.

Step-by-step explanation:

1. You have 4 pieces of wood, each 5ft long. 4*5 =20. You cut off 3ft off of each of the four pieces, or 4*3=12. 20-12=8ft left.

2. You cut 3ft off each of the 5ft long pieces of wood, leaving you with 2ft of wood as the remaining length of the pieces. 2ft of wood per each of the 4 pieces is 2*4 or 8ft in total.

This chapter addresses elements of above-grade structural systems in

residential construction. As discussed in Chapter 1, the residential construction

material most commonly used above grade in the United States is light-frame

wood; therefore, this chapter focuses on structural design that specifies standard

dimension lumber and structural wood panels (i.e., plywood and oriented strand

board sheathing). Design of the lateral force resisting system (i.e., shearwalls and

diaphragms) must be approached from a system design perspective and is

addressed in Chapter 6. Connections are addressed in Chapter 7, and their

importance relative to the overall performance of wood-framed construction

cannot be overemphasized. The basic components and assemblies of a

conventional wood frame home are shown in Figure 5.1; the reader is referred to

Chapter 1 for more detailed references to house framing and related construction

details.
