Answer:
The quadrilateral is not a parallelogram
Step-by-step explanation:
we know that
In a parallelogram opposite sides are parallel and congruent
Find the length of the sides of the quadrilateral
step 1
Find the distance QR
the formula to calculate the distance between two points is equal to

we have
Q(-10,-2), R(1,-1)
substitute



step 2
Find the distance TS
the formula to calculate the distance between two points is equal to

we have
T(-11,-8), S(1,-7)
substitute



we have that
QR and TS are opposite sides
In a parallelogram opposite sides are congruent but in this problem


therefore
The quadrilateral is not a parallelogram
Answer:
-$25.84
Step-by-step explanation:
254* -0.17 = -$43.18 profit from milk
51 * .34 = $17.34 profit from OJ
-43.18 + 17.34 = -$25.84 profit total
K. A quadrilateral has a total angle measure of 360. We know that two of the angles are 90, so we can subtract 180 from that. We’re left with 180. So we can make it into and equation. X+2x=180. Simplify and solve, and you get that x=60.
L. Again, a quadrilateral has a total of 360. So we can subtract the right angle from that and get 270. Put it into and equation, and you get x+2x+3x=270. Simplify and solve, and you get that x=45.
If the probability that an event will occur is 0, then the event is impossible to occur
Answer:
-7.21
Step-by-step explanation:
2.35-4.89= -2.54, 8.39-3.72=4.67, -2.54-4.67= -7.21
