you have 240 cubic inches of clay with which to make a sculpture shaped as a rectangular prism. You want the width to be 4 inche

s less than the length and the height to be 2 inches more than 3 times the length. What should the dimensions of the sculpture be.

Length=6, width=2, height=20. We can write a function to solve this problem. Suppose the length of the sculpture is x inches. Then the width is (x-4) inches, and the height (3x+2) inches. Their product is the volume of the clay: x*(x-4)*(3x+2)=240. Solve the equation, the only real answer is 6, so the length is 6 inches. Width is 6-4=2, and height is 3*6+2=20.

Answer:

Answer 1; Angles forming a linear sum to 180°

Answer 2; Substitution

Answer 3; Definition of perpendicular lines

Step-by-step explanation:

The two column proof is presented as follows;

Statement  {}                               Reason

1. ∠SWT ≅ ∠TWU {}                    Given

2. m∠SWT + m∠TWU = 180°  {}  Angles forming a linear sum to 180°

3. m∠SWT + m∠SWT = 180° {}    Substitution

4. m∠SWT = 90°  {}                      Algebra

5. \underset{TV}{\leftrightarrow }⊥ \underset{SU}{\leftrightarrow } {}                                  Definition of perpendicular lines

Perpendicular lines are defined as lines that are at right angles (90°) to each other, therefore given that the angle formed by the lines \underset{TV}{\leftrightarrow } and \underset{SU}{\leftrightarrow } m∠SWT = 90°, therefore, the lines \underset{TV}{\leftrightarrow } and \underset{SU}{\leftrightarrow } are perpendicular to each other.
