SV = 41 units.

QT = 21 units.

Step-by-step explanation:

To find the length of SV, we can first find the length of RV and TS.

RV = TR = 17:

3x + 2 = 17

Subtract both sides by '2':

3x = 15

Divide both sides by '3':

x = 5.

Plug this into the equation for TS, or 9x - 4:

9(5) - 4 = 41.

TS is congruent to SV, so SV also equals 41.

QT = QV, and QV is equivalent to '4x + 1' Plug in the value of 'x' we solved for:

4(5) + 1 = 21.

Therefore, QV and QT = 21.

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
