Answer:
x = 6
Step-by-step explanation:
AC = 5x - 24
AO = 3
AC and BD bisect each other at point O. This means AC ≅ CO.
So, 2(AO) = AC.
2(3) = 5x - 24
Multiply.
6 = 5x - 24
Combine the constants.
30 = 5x
Divide by 5.
x = 6
Answer:
x>=-3
Step-by-step explanation:
-4x-10<=2
-4x<=2+10
-4x<=12
x<=12/-4
x<=-3
x>=-3

Answer:
13 units
Step-by-step explanation:
The distance formula is useful for this.
d = √((x2 -x1)² +(y2 -y1)²)
d = √((5 -0)² +(8 -(-4))²) = √(25 +144) = √169
d = 13
The length of AC is 13 units.
