Answer:
A parallelogram
Step-by-step explanation:
The opposite sides and angles are congruent.
the maximum height is the y-value of the vertex.
h(x) = -2x² + 20x + 48
<em> a=-2, b=20, c=48</em>

h(5) = -2(5)² + 20(5) + 48
= -50 + 100 + 48
= 50 + 48
= 98
Answer: 98 meters
-v= -1v; -v÷-1 = k÷-1; The answer is v =k ÷ -1
The answer is 4 groups because 21+7=28,28÷4=7,and 7×4=28
the slope of line b is -2. this is because parallel lines share the same slopes, but different y-intercepts.
