Answer:
1/2 x -10 ≥ 0
Step-by-step explanation:
We know that a square root must have an answer that is greater that or equal to zero. The result of a square root cannot be negative. What is inside the square root must be greater than or equal to zero. To find the domain we solve that equation to determine the value of x.
1/2 x -10 ≥ 0
Perimeter of triangle is adding all three sides.
For example a triangle with sides 3, 5, and 7 would have a perimeter of 15
Now we use your values.
632 = (x) + (3x) + (3x + 2)
632 = 7X + 2
630 = 7x
90 = X
So side 1 is 90
Side 2 is 3(90) or 270
Side 3 is 3(90) + 2 or 272
Add all those up and you get (you guessed it) 632
