ABCD is an isosceles trapezoid with diagonals that intersect at point P. If AB || CD, AC = 7y -30, BD = 4y + 60, and CD = 5y + 14, find the length of CD
A. 124
B. 164
C. 180
D. 244

do you mean add both of the equations together

because if you do the answer is 10x-5

step-by-step explanation:

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
