um so you can just say what box if you dont want to explain i just think its all 3 if them one i figured out was wrong but the others i cant tell and i also suck at math

Table (4)

Step-by-step explanation:

If data in the given tables show the proportional relation then they will follow the rule,

y = kx

k =

where 'k' = proportionality constant

From table (1),

k = = 2

k =

But 2 ≠ 1.5

So the data in the table (1) is not proportional.

Table (2)

k =

k =

Therefore, data in the table is not proportional.

Table (3)

k = = Not defined

k =

Data is not proportional.

Table (4)

k =

  = 3

k =

3 = 3

Therefore, data given in table (4) represents the proportional relationship.

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)
