1. if quadrilateral abcd is a parallelogram, then which relation must be true?

a) m∠a = m∠b

b) m∠b = m∠d

c) ab = da

d) ab = bc

draw out the diagram and reference the fact that opposite angles and opposite sides are congruent in parallelograms

diagram is attached

step-by-step explanation:

here's what happens:

1) the graph of f   = x^2 is shifted 2 units to the right.

2) the resulting graph is reflected in the x-axis, so that the parabola now opens down.

3) this final result is transformed up by 5 units.

7

step-by-step explanation:

the answer would be 7

first, let's see what the pattern is.

58 - x = 47

46 - x = 36

x = 9

so this means that the term after 25 is 25 - 9:

the next term in the sequence is 16.
