Step-by-step explanation:
Given
Hypotenuse of isosceles triangle is 8 inches
In isosceles triangle two sides are equal
Suppose the other side is x
Using Pythagoras we can write
Therefore, the lengths of the legs is 5.6 inches
Answer:14
Step-by-step explanation:
Answer:
y² - (K- 2)y + 2k +1 = 0
equal roots means D=0
D= b^2 - 4ac
a=1, b= (k-2), c= 2k+1
so,
(k-2)^2 - 4(1)(2k+1) = 0
=> k^2 +4 - 8k -4 = 0
=> k^2 -8k = 0
=> k^2 = 8k
=> k= 8k/k
=> k = 8
Therefore the answer is k= 8

Answer:
x = -2 ±√5
Step-by-step explanation:
You want to complete the square by adding the square of half the coefficient of the linear term:
x^2 + 4x + (4/2)^2 = 1 + (4/2)^2
(x +2)^2 = 5 . . . . . simplify
x +2 = ±√5 . . . . . . take the square root
x = -2 ±√5 . . . . . . subtract 2. This is the solution.
