Answer:
REALS. all real numbers are solution for the equation
Step-by-step explanation:
for the equation
x² = (x + 3)*(x − 3) + 9
distributing the terms in the parenthesis
x² = (x + 3)*(x − 3) + 9 = [x² - 3*x + 3*x - 3*3 ] + 9
x² = x² - 9 + 9
0 = 0
since this statement will be true regardless of the value of x , then the equation has solution for all real numbers .
The percentage of change from 45 to 56 is 24.4%
To find this, we first need to find the difference between our two values. This difference would be 11.
The next step would be to divide 11 by 45. We then move the decimal point over two spots to the right which gives us our answer.

Step-by-step explanation:
Triangle midline theorem: In a triangle, the midline joining the midpoints of two sides is parallel to the third side and half as long.
Points M, N and K are midpoints of the sides AB, BC and AC. Acording to the Triangle midline theorem,
The perimeter of the triangle MNK is
