Answer:
EF=6
Step-by-step explanation:
E is the midpoint, so DE = EF
DE = 15-3x
EF = x+ 3
Since DE = EF,
15 - 3x = x + 3
-4x = -12
x = 3
If x = 3,
DE = 15 - 3*3, 15 - 9 = 6
EF = x+ 3, so EF = 3 + 3 = 6
Answer:
x = 2
Step-by-step explanation:
Given
3(x + 6) = 24 ( divide both sides by 3 )
x + 6 = 8 ( subtract 6 from both sides )
x = 2
