Answer:
8/8
Step-by-step explanation:
4/4 = 1
8/8 = 1
you can also see it in the number line that 4/4 and 8/8 are located in the same place.
The answer is that it's a right triangle. One angle is 90°
Slope RS: 2/3
Slope ST: -3/2
Slope TU: 4/6 = 2/3
Slope UR: -1/5
Sides RS and TU have the same slope, so they are parallel.
The slope of side ST is the negative reciprocal of the slopes of sides RS and TU, so side ST is perpendicular to sides RS and TU.
Side UR is not parallel or perpendicular to any other side.
The quadrilateral is a trapezoid.
Answer:
18
Step-by-step explanation:
x-5=(x+8)/2
x-5=x/2+4
add 5
x=x/2+9
subtract x/2
x/2=9
times 2
x=18
