Find a formula for an arithmetic sequence that begins 45, 40, 35, 30, ... a) qn = 40+5n
b) qn = 50-51
c) 9n = 45-5(n-5)
d) 9n=45-5n

Find the missing dimension! need asap! tiny square is a =3025 in ²

Look at the figure below: triangle abc is a right triangle with angle abc equal to 90 degrees. the length of ac is 5 units and the length of ab is 4 units. d is a point above c. triangle adc is a right triangle with angle dac equal to 90 degrees and dc parallel to ab. what is the length, in units, of segment cd?

Pls the last one and it has to be like number 6
