Answer:
Choice A
Step-by-step explanation:
You can rule out choices B and D because they do not have 6 sides which your prism does. You can forget about C being correct because it doesn't have 4 long sides.
Answer:
One
Step-by-step explanation:
Line of symmetry of a figure is an imaginary line about which the figure can be divided into two equal halves.
In other words, a line passing the center of the figure about which we can fold the figure into two halves overlapping each other.
For the trapezoid given in the figure, line of symmetry will be a vertical line perpendicular to the parallel sides.
Therefore, The figure has 1 line of symmetry.
Answer: 
<u>Step-by-step explanation:</u>
For this case, the first thing we must take into account is the following definition:
d = v * t
Where,
d: distance
v: speed
t: time
Substituting values we have:
Trip 1:
50 = v * t1
We cleared t1:
t2 = (50) * (1 / v)
Trip 2:
300 = (3 * v) * t2
We cleared t2:
t2 = (300/3) * (1 / v)
t2 = (100) * (1 / v)
Rewriting:
t2 = 2 (50) * (1 / v)
t2 = 2 * t1
Answer:
His new time compared with the old time was:
Twice the old time.
t2 = 2 * t1.
The answer to the question is 14
x^4 + 14x^2 + 49
(x^2 + 7)^2
perfect square
