Which is the equation of a parabola with a directrix at y = -3 and a focus at (5, 3)?

a. y=1/12(x-5)²
b. y=-1/12(x-5)²
c. y=1/12(x+5)²
d. y=-1/12(x+5)²

hi,

3. 12.15, you are correct.

4.2.01, your first digit is correct,

hope this !

i can you with this question sweetie!

step-by-step explanation:

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)
