Point P is the midpoint of DE⎯⎯⎯⎯⎯ . DP=3x+2, and DE=10x−12. What is the length of DP⎯⎯⎯⎯⎯ ?

Respuesta :

DP =1/2DE, 3x+2=1/2(10x-12).
3x+2=5x-6
x=4
So DP=3(4)+2=14.

Midpoint is the point that divides a segment, line or shape into 2 equal sections. The length of DP is 14 units

Given that:

[tex]DP = 3x + 2[/tex]

[tex]DE = 10x - 12[/tex]

P is the midpoint means that:

[tex]DE = 2 \times DP[/tex]

So, we have:

[tex]10x - 12 = 2 \times (3x + 2)[/tex]

Open bracket

[tex]10x - 12 = 6x + 4[/tex]

Collect like terms

[tex]10x - 6x = 12 + 4[/tex]

[tex]4x = 16[/tex]

Divide both sides by 4

[tex]x =4[/tex]

Recall that:

[tex]DP = 3x + 2[/tex]

So:

[tex]DP = 3 \times 4 + 2[/tex]

[tex]DP = 14[/tex]

Hence, the length of DP is 14 units
