Plz scale factor triangle a. 10.5 cm b. 31.5 cm c. 63 cm d. 189 cm

If two similar triangles have sides in the ratio a : b, then their areas are in the ratio a² : b².

We have the ratio:

Area of the smaler triangle = x

Area of the larger triangle = 567 cm²

Therefore we have the equation:

(w – 2.5)(w + 2.5)

(–4v – 9)(–4v + 9)

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
