Which best describes the relationship between the successive terms in the sequence below?

–3.2, 4.8, –7.2, 10.8, …

The terms have a common difference of 8.
The terms have a common difference of 1.6.
The terms have a common ratio of –1.5.
The terms have a common ratio of –0.67.

the terms have a common ratio of - 1.5

Step-by-step explanation:

Consider the ratio between consecutive terms

4.8 ÷ - 3.2 = - 7.2 ÷ 4.8 = 10.8 ÷ - 7.2 = - 1.5

answer: i guess 105 degrees?

step-by-step explanation:

answer is 8x+24

area of vanessa's patio = length × width

given, length = (3x² + 5x + 10)

width = (x² - 3x - 1)

area of vanessa's patio = (3x² + 5x + 10)(x² - 3x - 1)

= 3x²(x² - 3x - 1) + 5x(x² - 3x - 1) + 10(x² - 3x - 1)

= 3x⁴ - 9x³ - 3x² + 5x³ - 15x² - 5x + 10x² - 30x - 10

= 3x⁴ - 4x³ - 8x² - 35x - 10

hence, expression of vanessa's patio = (3x⁴ - 4x³ - 8x² - 35x - 10)
