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
