Answer:
The smallest whole number length is 12
Step-by-step explanation:
The sum of any two sides of any triangle must be greater than the length of the third side.
In this case, the two smallest sides of the triangle must be greater than the third side to satisfy the statement above.
Let "x" = the length of the third side.
Our two smaller sides are "x" and "4", and their sum must be greater than 15.
x + 4 > 15
x > 15 - 4
x > 11
If you are solving for x then here’s how:
(3x2 + 4x - 12) = (x + 5)
Remove the x on the left by remove one x from both of the sides.
(3x2 + 3x - 12) = 5
Add 12 onto both sides
(3x2 + 3x) = 17
Multiply
(6 + 3x) = 17
Take away 6 from both sides
3x = 11
Divide by 3 on both sides
x = 3.666 recurring
