Area of a rectangle is the product of length times width. Thus, here we need the product of 8 1/2 inches by 11 inches.
One way of doing this follows: 8.5
8.5
----------
93.5 square inches
Rounding up, this comes out to 94 square inches.
Alternatively: 17 187
---- * 11 = ------- = 93.5 square inches; rounded, that's 94.

Answer:
131x
Step-by-step explanation:
7x² + 6x + 9x² - 5x
49x + 6x + 81x - 5x
136x - 5x
131x
5/8 * 125/125 = 625/1,000 = 0.625
62.5 percent
Solution: 62.5%
Answer:
x = -3, x = 0 is a extraneous solution
Step-by-step explanation:
Step 1: Cross-multiply
3x² = 4x² + 3x
Step 2: Isolate <em>x</em>'s
0 = x² + 3x
Step 3: Factor
0 = x(x + 3)
Step 4: Find roots
x = 0, -3
Step 5: Double check work
Plug in both to see if they both work. Only x = 0 should be extraneous. We now have our answer!
