Answer:
x=8
Step-by-step explanation:
3(x+4)=36
Divide each side by 3
3/3 (x+4)=36/3
x+4 = 12
Subtract 4 from each side
x+4-4 = 12-4
x = 8
C. The Triangle Inequality Theorem States that any two sides of a triangle must be greater than the third side. It cannot be A because 35+40= 75, which is not greater than 75. It cannot be B because 40+30= 70, which is not greater than 75. It cannot be D because 35+40= 75, which is not greater than 80. It is C because 40+30= 70, which is greater than 65.
