A trapezoid is defined as a quadrilateral with only 1 pair of parallel sides. Since your Quadrilateral has 2 pairs, it can't be a trapezoid.
Answer:
8.63 square units
Step-by-step explanation:
you must set up a proportion.
3 x
- = -
8 23
after you set up that proportion, cross multiply to find x.
8x = 69
divide by 8
x = 8.625, rounded to 8.63
Answer:
Step-by-step explanation:
The two photos are attached for the missing information in your question.
Statement: m∠7 and m∠8 are supplementary.
Reason: Linear Pair Theorem
Domain of

are the values of x for which 2x + 1 < 0
2x < -1
x < -1/2
Therefore, domain is all real numbers less than -1/2
