Slope is rise over run, and rise is the change of y.
QR || ST & QT=RS
That could be an isosceles trapezoid. Don't check this one.
QR=ST & QR || ST
Congruent Parallel sides. CHECK ME.
QT || RS & QR=ST.
Basically the same as the first, don't check.
QR=ST & QT=RS
Quadrilateral with equal opposite sides is a parallelogram. CHECK ME
QR=ST & ST=ST
ST=ST is not news. Congruent opposite sides. Don't check me.

Answer:
Step-by-step explanation:
The formula for determining the area of a rectangle is expressed as
Area = length × width
Their backyard is rectangular, with a length of 3x – 5 feet and a width of 4x – 10 feet. This means that the area of the backyard is
(3x - 5)(4x - 10)
= 12x² - 30x - 20x + 15
= (12x² - 50x + 15) square feet
Their rectangular swimming pool, along with its surrounding patio, has dimensions of x + 8 by x – 2 feet. This means that the area occupied by the swimming pool and its surrounding patio is
(x + 8)(x - 2)
= x² - 2x + 8x - 16
= x² + 6x - 16
Assuming the swimming pool and its surrounding patio will not be covered with new grass, then the area of the region of the yard that they want to cover with new grass is
12x² - 50x + 15 - (x² + 6x - 16)
= 12x² - 50x + 15 - x² - 6x + 16
= 12x² - x² - 50x - 6x + 15 + 16
= 11x² - 56x + 31 square feet
