The numerical value of x in the expression for the side length measure of the parallelogram is 6.
The figure in the image is a parallelogram.
A parallelogram is simply a quadrilateral having two pairs of parallel sides. Note that its opposite or facing sides are of equal length and the opposite angles are also of equal measure.
From the figure;
Side length WV = 7
Side length UX = x + 1
Now, since side lengths WV and UX are equal in measure, we simply equate the two side lengths and solve for x:
Side length WV = Side length UX
Plug in the values:
7 = x + 1
Now, to solve for x, subtract 1 from both sides of the equation:
7 - 1 = x + 1 - 1
6 = x
x = 6
Therefore, the value of x is 6.
