If the base is represented by the expression 4x+2 and the height is represented by 3x which expression gives the area a triangle

Area of a triangle = 3x* (4x+2)/2 = ( 12 x^(2)+ 6x)/2

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
