4x + 6y + 60 = 0
y intercept =
x intercept =

x = -15

y = -10

Step-by-step explanation:

To find the x intercept, we have to substitute 0 into y

4x + 6(0) + 60 = 0

4x + 0 + 60 = 0

4x + 60 = 0

4x = -60

x = -15

To find the y intercept, we have to subsitute 0 into x

4(0) + 6y + 60 = 0

6y + 60 = 0

6y = -60

y = -10

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)
