Add another triangle to make it a square/rectangle. Then find the perimeter of that. Then divide the answer by 2. That will be the perimeter of the shape.
The sum of twice a number (x^2)
and 5 less than the number -5
is the same as =
the difference between 17 and the number 17-x
(x^2) - 5 = 17 - x
If this is what you have in mind
(1/2)x + 5 = 9
Then solving this is quite simple
1st subtract 5 from both sides
(1/2)x = 4
Now divide 1/2 by both sides
x = 8
Answer:
Step-by-step explanation:
Your equation comes out to x + 3 = x/3. Multiplying all three terms by 3 results in 3x + 9 = x, which simplifies to 2x = -9, so that x = -9/2.
