Answer:
8x+12
Step-by-step explanation:
To find the Perimeter, we need to add all 4 sides together. In this case, we would do:
x+4+x+4+3x+2+3x+2
Now, we have to combine like terms.
x+x+3x+3x=8x.
4+4+2+2=12
The final answer would be 8x+12 or 12 +8x.
You can put whichever answer you want because it doesn't matter.
Hope this helps!

Answer
The exact solution of x is 2.65 for the given equation 3x² + 7 = 28 .
Step-by-step explanation:
The equation given in the question is as follows.
3x² + 7 = 28
Now simplify the above eqaution
3x² = 28 - 7
3x² = 21

x² = 7


x = 2.65
Therefore the solution for x is 2.65 for the given equation 3x² + 7 = 28 .
