Answer:
6 ugly
Step-by-step explanation:
6 x 3 equals 18
-9/ 3= -3
-3 + -4 + -2 = -9
the numbers are -2 , -3 , -4
Answer:
x= -4
Step-by-step explanation:
Answer:
x=4
Step-by-step explanation:
It suffices to equate any two sides and then check whether the solution is valid for the third side.
Taking 2x and 3x-4 and equating:
2x = 3x-4
x = 4
This means the sides are both of length 8. Now check whether for x=4 the third side is also of length 8:
x+4=4+4=8
which indeed works out confirming x=4 being a valid solution
