17/3

3(n+2)+3=2(3n-4)

3n+6+3=6n-8

17=3n

n=17/3

n = 17/3

Explained...

3(n+2)+3 = 2(3n-4)

3n+6+3 = 6n-8

3n+9 = 6n-8

9+8 = 6n- 3n

17 = 3n

3n = 17

n = 17/3

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)
