Answer:
- PQRS - a parallelogram
- GHJI - not necessarily
- RSUT - a parallelogram
- ABDC - a parallelogram
Step-by-step explanation:
A parallelogram has these characteristics that can be useful for answering this question:
- opposite sides are the same length
- opposite sides are parallel
- the diagonals bisect each other
__
<h3>PQRS</h3>
Opposite sides are the same length: a parallelogram
__
<h3>GHJI</h3>
Two isosceles triangles share a base segment. Not necessarily a parallelogram.
__
<h3>RSUT</h3>
The diagonals bisect each other: a parallelogram
__
<h3>ABDC</h3>
Opposite sides are parallel: a parallelogram. We know BD║AC from the converse of the alternate interior angles theorem. AB and CD are marked parallel.
Answer:
Step-by-step explanation:
Another way to solve would be to distribute first:
22 = 2(x + 6)
22 = 2x + 12
Subtract 12:
22 - 12 = 2x - 12
10 = 2x
Divide by 2:
10 / 2 = 2x / 2
5 = x
Answer:
Step-by-step explanation:
A={1;-6;1/2}
Assuming the missing signs are pluses, that would work out to a^3 + 12a^2 + 14a + 5
Answer:
y = |x| - 4
Step-by-step explanation:
this translates the function y down by 4 as is required
