Answer:
C) The square root of terms separated by addition and subtraction cannot be calculated individually.
Step-by-step explanation:
sqrt(b² - 4ac) is not equal to
b - sqrt(4ac)
Because when you square b - sqrt(4ac), it's not b² - 4ac..
(b- sqrt(4ac))² = b² - 2bsqrt(4ac) + 4ac
4/11 because when you multiply 5x4x you get 20x , so 8-2x=20x. Then you move the terms with variables and get -2x-20x=-8. This gives you the answer that -22x=8 and when u divide by 22 to both sides, you get 4/11.
If I read that right:
(3/5)/(-4/9) is equal to
(3/5)*(9/-4)
-27/20
-1 7/20
Answer:
