Write an expression for the area of a triangle with a height of 2x^2 units and a base of 5x^2+4x units

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

think the answer is 30 degrees. if not than it is 20 degrees. not 100% sure. let me know if it was right.
