Quadrilateral QRST is a parallelogram. Determine the measure of QRS

x=9

Step-by-step explanation:

In a parallelogram, opposite angles are equal.

So that means

2(3x - 4) = x + 37

6x - 8 = x + 37

5x = 45

x = 9

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
