2 times the cube root of 8x+9=5
divide both sides by 2
cube root of 8x+9=2.5
cube everybody (put to 3rd power)
8x+9=2.5^3
8x+9=15.625
minus 9 both sides
8x=6.625
divie both sides by 8
x=0.828125
1/6 = 0.1666, the last number repeating to infinity, or a repeating decimal.

Answer:
112 if you don't include the triangle sides as they are not necessary, but 124 if you include one triangle and 136 if you include both triangle sides
A perpendicular bisector forms two right angles and splits the line in two equal parts.
The altitude does create two right angles, but doesn't have to create two equal parts.
Answer:
y = 5
Step-by-step explanation:
3(у - 3) - 2(у -4) = 4
Distribute
3y -9 -2y +8 =4
Combine like terms
y -1 =4
Add 1 to each side
y-1+1 = 4+1
y = 5
