Acarpenter cuts the corners of a rectangle to make the
trapezoid shown.
what is the value of x?
(9x)
y (7x + 4)º

The value of x is 11.

Step-by-step explanation:

We can see from the diagram attached that the 9x° and the (7x+4)° are co-interior angles.

The reason is that, the two bases of the trapezoid are parallel.

Co-interior anlges or same side interior angles are supplementary.

This implies that:

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
