Left to Right
Step 1: Write expression
7 + (5 - 9)2 + 3(16 - 8)
Step 2: Parenthesis (subtraction)
7 + (-4)2 + 3(8)
Step 3: Parenthesis (multiplication)
7 - 8 + 24
Step 4: Subtract
-1 + 24
Step 5: Add

The dimensions are 8 and 7 square inches because 7 times 8 is 56.
The answer is 30
40 times 3/4 is 30
40 times .75 is also 30
A = length · width
7x3 - 42x2 = L(7x2) Factor left side
7x2(x - 6) = L(7x2) Divide both sides by 7x2
x - 6 = L
The length of the pool is x - 6.
Note: Length is always longer than width. Although the algebra is correct, it is doubtful that x - 6 is greater than 7x2.
