Answer: Yes
<u>Step-by-step explanation:</u>
In order to form a triangle, the sum of two sides must be GREATER than the third side.
a + b > c & a + c > b & b + c > a
5 + 2 > 4 & 5 + 4 > 2 & 4 + 2 > 6
True True True
The sides 5, 2, 4 satisfy the rules for forming a triangle.
Answer:
x = -5
Step-by-step explanation:
9x - 7 = -52
we want to single out x,
add 7 to both sides to be one step closer to getting x alone
9x - 7 + 7 = -52 + 7
9x = -45
divided both sides by 9 to get x alone
9x / 9 = -45 / 9
x = -5
Let me know if you need any clarification!
Step-by-step explanation:
x = 0 (I don't know what the result of this operation is and I need it to know the x but that's what I can do)
