Answer:
Just leave it how it is, you don't have to do anything with the negative symbol.
Answer:
find the exact value using trigonometric identities 0.6427876
Step-by-step explanation:
An algebraic statement that represents all the ways Eric will wins is , where be the number that Eric thinks and be the number that Nita thinks.
If the difference between their two numbers is less than, then Erik wins. If the difference between their two numbers is greater than, then Nita wins.
Let be the number that Eric thinks and be the number that Nita thinks.
For to Eric to win, the difference in the numbers should be less than.
That is, , for or , for .
Or .

Erik- |x-y|<10
Nita- |x-y|>10
a 40°
b 46°
c 134°
d 90°
a. (x+2)^2=20
b. (x+1)^2=23
c. (x+1)^2=20
d. (x+2)^2=23
Answer:
c.
Step-by-step explanation:
Since, for getting a perfect square on the left side of a quadratic equation we follow the following steps,
Step 1 : Make 1 as the coefficient of .
Step 2 : Add both side the square of a number which is half of the x's coefficient.
Given equation,
-----(1)
Here, the coefficient of is already one.
And, the middle term is 2,
Half of 2 is 1
Also, 1² = 1
Thus, add 1 on both sides of equation (1),
( Because (a+b)² = a² + 2ab + b² )
⇒ Option C is correct.
