Can anyone pls help me in this pls I will mark u as brainliest

13.83

Step-by-step explanation:

AC = 3 - (-2) = 5

CB = 4 - 1 = 3

AC ⊥ CB

AB = √5² + 3² = √34 = 5.83

perimeter: 5 + 3 + 5.83 = 13.83

next question, use the formula d = √(x - x')² + (y - y')²

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)

she was supposed to add the hours(38.5) and multiply the amount of money she earned(7.50) resulting in $288.75 .

correct me if i'm wrong and if it is i'm truly sorry.
