1. Can you use the expression from part c in exercise (#3) to find the surface area of the treasure chest in exercise 2? Explain

2. Find the area of the base of the treasure chest in square feet.

Answers

Answer:

The surface area of chest 2 would be 32 ft. The area of the base would be 6 ft

Step-by-step explanation:

If the shape is a square then multiplying the base by 6 would work but it is a rectangle in this case which  means some sides are uneven. 4 sides are 6 ft and the other 2 are 4. So 6 x 4 plus 4 x 2 would equal 32

37x  = 180 -2 +3+4

37x = 185

x = 185/37 =  5

Second angle =(12x-3 ) = 57

Third angle = (13x-4) = 61

how is solving inequalities with addition and subtraction similar to and different from solving equations with addition and subtraction?

Answers

That technique for solving equations is: Whatever you do to one side of the equation, you have to do to the other side to preserve the equality The technique for solving inequalities is: Whatever you do to one side of the inequality, you have to do to the other side to preserve the inequality. the techniques are the same. The difference between solving equations and solving inequalities is: If you multiply or divide an inequality by a negative number, then the inequality reverses. !!!!!
