6.5x-4.5x = 6+10
2x = 6+10
Divide both sides
2x = 16
X= 8
Answer:
x=2;DE,EF=9,DF=5
Step-by-step explanation:
Since DEF is isoceles, you can set the equations
x+7 and 2x+5 equal to each other
x+7=2x+5, now solve for x
-x=-2,
x=2, now plug in for each side
DE,EF=9
DF=3(2)-1=5
Answer:
47 and 49
Step-by-step explanation:
