3 0

Answer:

<h3>c = 25</h3>

Step-by-step explanation:

Given this quadratic expression.

x² – 10x + c = 0

We are to find the value c that will make the expression a perfect square'

Using the completing the square method

Add the square of the half of coefficient of x

Coefficient of x = -10

Half of -10 = 1/2(-10) = -5

Square of -5 = (-5)^2 = 25

Hence the value of c to complete the expression is 25

Find tje distance between the points (-10, 10) and (-4, 2).
VikaD [51]

The formula of a distance between two points:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

We have the points (-10, 10) and (-4, 2). Substitute:

d=\sqrt{(-4-(-10))^2+(2-10)^2}=\sqrt{6^2+(-8)^2}=\sqrt{26+64}=\sqrt{100}=10

<h3>Answer: d = 10</h3>
