What do I put in the box explain your answer

y=-2x+20

Step-by-step explanation:

Slope is -2 or 20/-10 because if you find two points on the graph, I used two that weren't in-between then u find that for every rise of 20 you go to the left 10. That means that the slope is 20/-10, simplify and get -2 as your slope. Right now you equation is y=-2x+b

Then to find the y intercept or b plug in any point from the graph. I used (40,100). Plug that into the equation that we already have and you get b equals 20.

So your equation is y =-2x+20

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)
