We can do this by factoring: x^2 + 5x - 36, which is (x+9)(x-4)
We plug f(x) as 0, so (x+9)(x-4)=0, so x = -9 and x = 4
The x-intercepts are (-9, 0) and (4, 0).

Hope this helps!
It’s decreasing 2 degrees per hour. It’s starting at 82 degrees. The first hour decreases to 80 degrees. It’s hard to explain but the slope is -2 degrees per hour.
Length×width≈area
1620×68≈110160cm²
