Use deductive reasoning to select a valid conclusion. If a quadrilateral is a rhombus, then it is also a parallelogram. Quadrilateral ABCD is a rhombus. A. Quadrilateral WXYZ is a rhombus
B. No valid conclusion
C. Quadrilateral ABCD is a parallelogram
D. Every quadrilateral is a rhombus

hi! i think the answer is 1/2 : )

im guessing (23,14). hope this : )

i would be 2,000 just get the square root of 50 which is 2500 and the divid 4/5 and last thing multiply the answer you get for that by the square root of 50

step-by-step explanation:

since no one answered yet i will give it a shot, not completely sure tho.

i think it should be y=cos(x+2pi), (third answer, answer c)

good luck.
