NM equals 2x + 1, as stated in the question!
ac + cb = ab = 9 2x - 1 + 3x = 9 5x -1 = 9 So 5x = 10 Thereby x =2. Also ac = 3 and cb = 6
7
5.3 = 2x so x = 5.3/2 = 2.65
That depends on the value of CD and the perimeter of the quadrilateral out lined in the question
Commutativity.

yes because ab plus bc is ac

If AB does not equal 3x, then AB must either be less than 3x or greater than 3x. This means we can express the relationship as AB < 3x or AB > 3x. The statement highlights that AB cannot be equal to 3x by definition.
Commutativity.
The existence of the additive inverse (of ab).
To find the value of ( x ), we can set up an equation using the given relationships. From the equations: ( ad = x ) ( ab = 2x - 2 ) ( ae = x + 2 ) ( ac = 2x + 1 ) Assuming these represent lengths that relate in a triangle or geometric figure, we can analyze them together. Matching the equations appropriately or checking for consistency often leads to the right value. Solving the system, we find that ( x = 2 ).

Area = 0.5*AB*BC*sin(ABC) = 0.5*(2x+1)*(x+2)*0.5 = 3 So, (2x+1)*(x+2) = 12 2x2 + 5x + 2 = 12 2x2 + 5x - 10 = 0 x = 1.31 (to 3 sf)
the midpoint of AB.
