Answer:
The first one: the error was that the 3 shouldn’t have been moved but the 5 should have. The correct answer is k=-8
The second one: the error was that they added the 6 and 4, you would only get -10 if the 4 was - the correct answer is -2
You can check your answer by plugging in your answer to the variable and making sure both side equal each other
Step-by-step explanation:
The first one: the 5 should be - from both side so you get k=-8
The second one: the 4 should be + to both sides. And the -6 and +4 should be added together to get n=-2
Remember you always want to get the variables by themselves.
Sorry that was a lot. Hope it helps!
Answer:
3,1. 4,2. 4,3. 1,1 (kkkkkkkk) no importance for kkkkkkkk
The given expression is in the form (a+b)(a-b) where
a = 5
b = sqrt(3)
Recall that
(a+b)(a-b) = a^2-b^2
is the difference of squares formula
If a = 5, then a^2 = 25
If b = sqrt(3), then b^2 = (sqrt(3))^2 = 3
The squaring undoes the square root. The two opposites cancel out.
So using a^2 = 25 and b^2 = 3, we can say
(a+b)(a-b) = a^2-b^2 = 25-3 = 22
Therefore,
(5+sqrt(3))(5-sqrt(3)) = 22
Answer: B) 22
Answer:
a > b
Step-by-step explanation:
3 > -2
a > b
