Un trapèze a une aire de 39 cm2. sa grande base
mesure le triple de sa petite base. sa hauteur
mesure 3 cm.
trouve les dimensions des bases de ce trapèze.

A = bh/2

39 = b*3/2

39*2 = b*3/2 * 2

78 = b*3

78/3 = b*3/3

26 = b.

Alors, la grande base est 26 cm et le petit base serait 26/3 = 8.67 cm arrondi.

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
