Answer:
Step-by-step explanation:
- √(14 - 2√13) * √(14 + 2√13) =
- √(14 - 2√13)(14 + 2√13) =
- √(14² - (2√13)²) =
- √(196 - 4(13)) =
- √(196 - 52) =
- √144 =
- 12
<h3><u>Part A</u></h3>

factor the common term 'y' and '-4'

collect into groups

<h3><u>Part B</u></h3>

middle term split

factor the common term '3x' and '-2'

collect into groups

simplify the following

Total checkers = 2 + 6 = 8
P(black, then red) = (6/8)(2/7) = 3/14
Answer: 3/14
