A quadratic equation that has 2 roots that are equal means that the discriminant of the equation is 0. The value of k that makes the equation have 2 real and equal roots is
Given that:
Rewrite as:
A quadratic equation is represented as:
By comparison:
If an equation has 2 real and equal roots, then:
So, we have:
Divide by 4
Divide by 6
Subtract 2 from both sides
Take LCM
Divide by 2
Hence, the value of k that makes the equation have 2 real and equal roots is

Answer: 101.5
11x6.5 = 71.5
6x5 = 30
Add together the products
Given:
Surface area = 4,362 yards
Length = 36 yard
Width = 21 yard
Height = c
To find:
Volume of the rectangular prism.
Solution:
Surface area formula:
Substitute the given values.
Subtract 1512 from both sides.
Divide by 114 on both sides, we get
25 = c
Height = 25
Volume = length × breadth × height
= 36 × 21 × 25
= 18900
Volume of rectangular prism is 18900 cubic yards.
In a parallelogram we know that co-interior angles are supplementary
That is, sum of Angel A and Angle D=180
So , in the given question, it is given that, Angle A=46 and angle D=100
Since , the sum is not 180
=> the answer is false..!!
Hope this helps you!!!
Answer: Endpoint = (-4,6)
Step-by-step explanation:
To find any endpoint use the formula
multiply each by 2 to simplify
take the equations and simplify
6+ = 2 -2+ = 4 =
-6 -6 +2 +2
= -4 = 6
To check use the Midpoint formula
