Answer:
AB = 25 units
Step-by-step explanation:
In right triangle ACB,
Therefore, by geometric mean property:
AB = AD + DB
AB = 20 + 5
AB = 25 units
To solve this simply divide 4 by 3 and use the long division and do the same for 11 and 9, then compare the values.
-3 1/3,
think about it as money. would you rather owe someone 3 dollars, or 1 dollar.
Also, -4/5 is closer to zero, so you know its more than -3, that's farther away (number line)
In conclusion, -3 1/3 is less.
Answer:
1. A resposta é a opção C.
2. ( a +b )² = a² + 2ab + b² Verdade
( a - b )² = a² - 2ab + b² Verdade
( a + b ) .( a – b) = a² + b² Falso
( a +b)³ = a³ + 3a²b + 3ab² + b³ Verdade
( a -b)³ = a³ - 3a²b + 3ab² - b³ Verdade
3. a.) m² - 14am + 49a² = ( m - 7a)²
b) m2 – 9n² = m² - (3n)² = (m + 3n)(m - 3n)
c) 30+ 5xy + 12a +2axy = (6 + xy)(5 + 2a)
d) 8a²b + 10ab² = 2ab( 4a + 5b)
