Solve for x: 5x+12−2x=24.
A) 4
B) 5
C) 6
D) 7
A) 4
Explanation:
1. Combine like terms:
5x + 12 - 2x = 24
(5x - 2x) + 12 = 24
3x + 12 = 24
2. Isolate x:
Subtract 12 from both sides of the equation:
3x + 12 - 12 = 24 - 12
3x = 12
Divide both sides by 3:
3x / 3 = 12/3
x = 4

a) Acute triangle
b) Equilateral triangle
