When the scientist put in 50 ml of solution, the cell count was 205. when 40 ml of solution was used, the cell count was 200. which equation models this data

every 10 mL of solution equals 5 cells

Step-by-step explanation:

I'm not sure if this equation is right but I think it's either 200÷40, 205÷50, or 205÷40 I hope this is kinda helpful.

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)
