Answer:
6xy(15xy−1)
Step-by-step explanation:
27/7 or Decimal: 3.857143
there are 8 letters
2/8 to get i on the first draw
1/7 to get i on the second draw (no replacement)
2/8 * 1/7 = 2/56
1/28
The probability is 1/28
Answer:
2100 ft²
Step-by-step explanation:
1 yard is 3 ft, so 70 yards is (70 yd)×(3 ft/yd) = 210 feet.
The area of the pavement is the product of its length and width:
area = (210 ft)(10 ft) = 2100 ft²
_____
If you keep the units with the numbers as I have done here, you find that the product of (10 ft) and (70 yd) does not have the units of ft². Rather, the units are ft·yd, which is <em>not what the problem is asking for</em>.
