Which expression gives the distance between the points (2,5) and (-4, 8)?
german

Answer:

A. (2+4)² +(5-8)²

Step-by-step explanation:

To find then distance between two points, we will follow the steps below;

write down the formula

D = √(x₂-x₁)²+(y₂-y₁)²

(-4, 8)

x₁=-4

y₁ = 8

(2,5)

x₂=2

y₂=5

we can now proceed to insert the values into the formula

D = √(x₂-x₁)²+(y₂-y₁)²

   

   = √(2+4)²+(5-8)²

    =√(6)² + (-3)²

   =√36+9

   =√45

Therefore the expression which gives the distance between two the two points is  (2+4)² +(5-8)²

What constant do you need to add to each quadratic to complete the square?
babunello [35]

Answer:

1. 4

2. 16

3. 9

Step-by-step explanation:

Completing the square requires a quadratic in ax^2+bx=c form. Once in this form, calculate (\frac{b}{2})^2.

1. (\frac{b}{2})^2=(\frac{-4}{2})^2=4

2. (\frac{b}{2})^2=(\frac{-8}{2})^2=16

3. Requires you divide everything by 3 first.

\frac{3x^2+18x}{3} =\frac{249}{3} \\x^2+6x=81

(\frac{b}{2})^2=(\frac{6}{2})^2=9
