Mathematics

8 0

Answer:

x=5, -1

Step-by-step explanation:

set the equation equal to 0: 2x^2-8x-10=0

divide both sides by 2 to get x^2-4x-5=0

next factor your new equation to get (x+1)(x-5)

set those equal to zero

now you have x+1=0 and x-5=0

finally, solve for x by subtracting 1 and adding 5

now you have your answer x= 5 and -1

What triangle is formed by the points (3,2), (4,7), and (5,6)?
Sophie [7]

Answer:

Scalene Triangle

Step.-by-step explanation:

Calculate the lengths of the sides:

Side 1 = √((4-3)^2+(7-2)^2) = √26.

Side 2 = √((6-7)^2+(5-4)^2) = √2.

Side 3 = √((6-2)^2+(5-3)^2) = √20.

So each side is different in length and so its a scalene triangle.
