Step-by-step explanation:
Triangles DPA and DMU are similar
DP/DM = PA/MU
3.75/10 = 4.5/MU
MU = 4.5×10/3.75
MU = 12
Area = ½ × (4+10) × 12
½ × 14 × 12
84 units²
6

Answer:
X=2, Y=-15
Step-by-step explanation:
-7x+y=-19
-2x+3y=-19
------------------
-3(-7x+y)=-19
-2x+3y=-19
---------------------
21x-3y=57
-2x+3y=-19
---------------------
19x = 38
19x/19=38/19
x=2
now plug 2 into x of the second equation to get y=-15
