Answer:
3x-4y+3 is linear equation.
3×1-4×1+3
3-4+3
3+3-4
6-4
2
I think you mean
so therefor since we can't take squaer root of negative
3t-9 must not be negative
basicaly, 3t-9 must be greater than or equal to 0
The perimeter of a certain polygon is the sum of the measures of all its sides. If we are to use this concept with the given polygon above then that would be,
P = (3x + 1) + x + x + ?
We are also given that the perimeter is equal to 6x + 2. We substitute this to the equation derived,
6x + 2 = (3x + 1) + x + x + ?
Simplifying,
6x + 2 = 5x + 1 + ?
? = x + 1
Answer: The last side is equal to x + 1.
